Illustrated clip is a moulded parts of using the integral body of making such as the such suitable plastic material of polypropylene or nylon, has main body 10, one ends that a fixed hole 11 is arranged.

Stretch out a tongue 12 from the other end of main body 10, sawtooth 13 extension continuously on whole length of tongue is basically arranged on its upper surface.These sawtooth are preferably pressed the shape shown in Fig. 4 detail drawing and are shaped, and are being not have inside and outside circular arc between the vertical face 14 and domatic 15 basically.

From Fig. 1 and Fig. 3 as seen, tongue 12 is very thin thereby flexibility is arranged, and the both sides taper forms terminally 16 on its free end, and its upper surface does not have sawtooth.As shown in Figure 4, terminal top and bottom are at end chamfering, and convenient tongue penetrates main body 10, will be described below.

A passage 17 extending longitudinally in main body 10 is arranged, in the end of main body, the lower opening of tongue 12.This passage to the main body upper surface, arrives main body 10 bottom surfaces by aperture 19 openings by inlet hole 18 openings, and then arrives main body 10 upper surfaces by locking aperture 20 openings.On a sidewall of main body 10, be provided with a rectangular indentation 21 at locking aperture 20 places.

Having a locking member 22 to be provided with that side extending transversely of breach 21 and to dwindle the flexible of cross section with one from main body 10 partly 23 is connected on the main body; Locking member 22 be shaped as a rectangular block, its size prepares in the locking aperture 20 of packing into, and the surface is provided with sawtooth 13 and cooperates fully with the sawtooth on the tongue 12 thereon, be corresponding vertical surface and domatic be reverse.23 bendings of flexibility part can be pressed into locking member 22 in the hole 20, and serrated surface is towards passage 17, and flexible part 23 is included in the breach 21.

Connect partly and 23 can form an articulating point, with convenient joint bending at 28 place's attenuates.

Establish outstanding rib 29a near the place of serrated surface on each limit of locking member, when locking member entered hole 20, these ribs pushed through the outstanding flange 29b on this hole opposing sidewalls.This locking member just had been clamped in the hole 20 in placely in the past with the solid conduit of direct bearing or other member engages like this, and its upper surface exceeds on the main body 10.

Connecting partly 23 preferably has and locking member tool bullet is soared passage from the tendency of passage 17 allow tongue 12 enter.

Being sized to of passage 17 is enough to hold tongue 12, therefore tongue 12 can upwards bend inflection again and make end 16 enter inlet hole 18, then by arcwall 24 guiding inlet passages, and under domatic 30,31 and 32 guiding, pass passage and stretch out outside the main body, at this moment clamp end and be pulled outwardly with hand vice and so on.

Have a stopper 25 to be connected on the main body 10 by the part 26 that can pull apart, the size of stopper prepares in the fixed hole 11 of packing into, and a blind hole 33 is arranged therein.When using the bigger immobilising device of diameter such as screw or special fastener to fix, can use hole 11 as clip.When fixing with unit's nail or other minor diameter devices, in stopper insertion hole 11, again fastening piece is passed stopper as clip.The securing means that certainly adopts other or add.

Illustrated clip is made the electric conduit saddle clamp by following mode and is used.Clip is with suitable fastening piece fix in position recited above, and in locking member 22 patchholes 20, protuberance 29a and 29b block locking member in place.Also as described above tongue being passed passage 17 makes clip and catheter abutment around conduit with tongue 12 then.

With hand vice clamping end 16 tongue is pulled through from main body.At this moment conduit is pressed in the sawtooth that makes on the locking member 22 on the locking member downwards and is driven into the engagement on the tongue, and tongue is held below by cross a part 27 passage 17, main body 10 below hole 20 simultaneously.

The thickness of locking member 22 is to come so selected its upper surface that makes still to be on the circumferential surface of main body 10 it is placed on hole 20 in and when pressing tongue 12, and it is just with the solid member maintenance jointing state of direct bearing, as shown in Figure 5 like this.

When tongue was pulled through from main body, domatic 15 of sawtooth slipped over mutually, and the engaging force of locking member and tongue is increasing.So, when with tongue when conduit tightens up fully owing to be added in power on the locking member, and have the vertical surface of a plurality of intermeshing sawtooth to prevent the activity that retreats of tongue, so tongue is locked in the main body securely.

Be appreciated that the conduit diameter of clip applicable to a scope, the length of the tongue of being selected for use limits.

Be appreciated that and the conduit or other objects that clamp if can be deviate from from clip, just locking member can be deviate from or moved apart enough distance of tongue from the hole and throw off with tongue, but clip just overline use.

Shown in Figure 6 is a kind of remodeling of clip, and the clip of this structure helps its reusability, can remove the locking of clip under the situation that clip still follows conduit or its member engages.

In the present embodiment, breach part 21 is widened to the width in aperture 20, so locking member 22 can be pulled out from the hole along Fig. 6 direction of arrow from jointing state slidably outward.This can for example 23 realize by hauling with hand vice partly, and in the present embodiment, partly 23 can only be connected on the locking member.

Fig. 7 and 8 illustrates an alternative embodiment of the invention, and wherein locking member 22 constitutes a part of main body 10 upper surfaces, connects with main body by a hinge portion that fuses 34.
