Definitions
- the invention relates to a coupling between a first body with a cylindrical hole wifch -aa- ⁇ xis and a cylindrical end zone of a second body to be inserted therein in an axial insertion direction, in which hole and/or on the surface of which end zone extend a number of elastically deformable tongues which are fixedly connected to the relevant body and ordered in angularly regular manner, for instance equidistantly, the free end edges of which tongues lie substantially on the peripheral plane of an imaginary, substantially rotation-symmetrical body, respectively the diameter of which is. smaller than the outer diameter of the end zone of the second body or the diameter of which is greater than the diameter of the hole, which tongues extend at an angle to the axial direction such. that, when said end zone is inserted, they bend in the insertion direction and scrape over the surface thereof with their free edges such that after insertion of the end zone over, some distance the movement in backward direction relative to the insertion direction is blocked.
- the tongues can extend on the inner side of the hole but, alternatively, can also be situated on the 5 surface of said end zone. It is recommended for safety reasons when the coupling is effect-a ⁇ that the tongues are situated inside the hole, since there is otherwise the danger of the person effecting the coupling being injured by the possibly sharp tongues.
- the tongues can consist of any suitable material.
- a sufficiently strong plastic such as for instance ABS is therefore suitable.
- Cheaper and very reliable is an embodiment where the tongues consist of metal, in particular steel.
- the coupling according to the invention has the special feature that the tongues form part of a monolithic unit, also comprising a substantially flat ring which is at least partially received in- the wall of the hole of the first body.

- the coupling according to the invention has the special
- each tongue has a main direction in axial projection which differs from the radial direction and is in a direction opposite the direction of rotation when the end zone of the second body is moved outward.
- a more or less radially directed additional force is hereby exerted on each tongue during rotation of the cylindrical end zone of the second body, whereby the ring has a slight tendency to somewhat facilitates the helical rotation.
- the coupling according to the invention has the special feature that the hole has an axial stop for bounding the distance over which said end zone of the second body can be inserted into the hole.
- the coupling can be effected in very simple manner by inserting the cylindrical end zone of the second body with some axial force into the cylindrical hole in the first body, wherein the axial insertion distance is determined by said axial stop.
- This axial stop can for instance be embodied as an annular shoulder, against which the leading edge of the end zone of the second body comes to lie.
- the coupling has the special feature that the first body is a tube or tube stub.
- the coupling can have the special feature that at least said end zone of the second body consists of plastic, concrete, wood or metal, such as iron, copper or aluminium. It is important that the material of the tongues is chosen such that it can co-act effectively in the above described manner with the material of the second body.
- An embodiment which is easy to assemble has the specific feature that the ring has an interruption and is accommodated clampingly while being elastically deformed in an annular recess in the relevant wall of the relevant body.
- the above specified coupling can have for this purpose the special feature that the ring has a number of protrusions which during mutual rotation of the two bodies in the stated manner brace themselves against the material of the body to which the ring is fixedly connected.
- the annular recess can have a local interruption in the form of a stop wall, with which an end of the ring at the position of the interruption can co-act during sai-djs&atation. Unintended rotation of the ring is effectively prevented with both variants .
- a specific embodiment of the coupling according to the invention has the special feature that the ring is secured against rotation in both directions.
- Such a coupling is suitable for carrying out a method for establishing such a coupling, the method comprising the steps of: (a) displacing the surface of the related body over some distance in axial direction along the end edges; and
- the coupling has the special feature that upstream relative to the insert direction a sealing ring is present on the first or the second body.
- a sealing ring is present on the first or the second body.
- the coupling has the special feature that the sealing ring is accommodated in an annular groove broadening in the insert direction, in a way such that after inserting the cylindrical end zone of the second body in the hole and subsequently displacing same in the opposite direction the ring is caused to cooperate in a clamping and sealing manner with the bottom of the annular groove and the facing surface of the related body.
- a coupling according to the invention can for instance be applied for the coupling of two tubes .
- a two-sided coupling sleeve can thus for instance be coupled at both its ends to respective tubes by means of two associated couplings according. to the invention.
- Such a sleeve can optionally be an outer sleeve or an inner sleeve.
- an outer sleeve the connection between the tubes for coupling to each other can be realized such that these tubes come to rest with their free end edges against each other.
- suitable sealing means for instance sealing rings present on the inner surface of the outer sleeve.

- Fig. 8 shows a cross-section tfa «ugh a sleeve in a further embodiment
- Fig. 9 shows a view corresponding with Fig. 8 of a final embodiment .
- Fig. Ia shows a first tube 1 and a second tube 2.
- the first tube has an inner diameter corresponding to the outer diameter of the second tube 2 such that this second tube 2 can be inserted as far as an annular axial stop 3 into first tube 1.
- the axial insertion direction is indicated with an arrow 4.
- Lying on an annular shoulder 5 is a steel ring 6 which is provided with twelve inward protruding tongues 7 and which forms a monolithic unit therewith.
- Fig. 2a, 2b and 2c As shpwn clearly in Fig. Ia and Ib, tongues 7 have a position bent slightly downward in accordance with the insertion direction 4.
- ring 6 is fixed relative to tube 1 by means of a cylindrical fixation ring 8 which can be connected fixedly to tube 1 by means of screwing, glueing, welding or any other suitable process after insertion of ring 6. It is noted that ring 6 can also be embedded in the first tube 1, for instance if it is manufactured from plastic.
- the end edges 9 of tongues 7 have an inclining position corresponding to a part of a helix.
- This aspect can be seen particularly well in Fig. Ib and Fig. 2c.
- the direction 13 (see Fig. 4a) of the helix is formed during mutual rotation 12 of tubes 1 and 2 around axis 10 of hole 11, i.e. the internal cavity of tube 1, whereby an axial displacement 14 occurs, and end zone 15 of second tube 2 can be removed from hole 11 of the first tube.
