3 Claims. (Cl. 24-186) Devices for detachable attachment of textiles and the like are known, which consist of a metal clamp with points. These are hooked into the fabric and fastened under tension, i. e. of an elastic band. Such clamps have also become known in medical practice, especially for fastening bandages. However, a disadvantage of most of the known clamps is that the points stand out unprotected so that the skin of the user may become hurt, or at least an uncomfortable feeling results for the wearer.

According to the present invention, the points of the clamp are covered by a slide in order to avoid the above disadvantages. Thus it becomes not only impossible for the user to hurt himself, but this arrangement further guarantees positive securement of the fabric. This is of particular advantage with materials which become frayed easily, as is the case i. c. with fabrics like disposable diapers, thin muslin, etc.

The slide can be placed easily on the longitudinal bars of the metal clamp. Preferably it consists of a flat piece of metal tubing which is slid over the finished clamp and then pressed together. Indentations for the points of the clamp are provided. In order to guarantee a particularly firm attachment between slide and points it is of advantage that the points lie next to one side of the slide when it is closed, especially next to the inner sides of the indentations. For special purposes the points and the openings of the slide may also ofiset to one side of the plane of the frame.

In the drawings two forms of the invention are shown.

Fig. 1 is a perspective view of a clamp according to the invention.

Fig. 2 is a view on Fig. 1.

Fig. 3 is a section along IllIll of Fig. 2.

Fig. 4 is a section along lV-IV of Fig. 2.

Fig. 5 is a view of the clamps when in use.

Fig. 6 is a section along VI-VI of Fig. 5.

Fig. 7 is another form of the invention.

Fig. 8 is a section along VIII--Vlll of Fig. 7.

Fig. 9 is a section along IX-IX of Fig. 7.

In the figures, the metal frame-piece consists of the two bars 1 and 2, which are connected with each other 2,828,521 Patented Apr. 1, 1958 2 by the cross bars 3 and 4; on one side of the frame a strip 5 is bent up. The two points 6 and 7 on the cross bar 3 are offset according to the form of the invention illustrated by Figs. l-4, while they are on a level with the frame according'to the form of the invention illustrated by Figs. 7-9. The slide 8 is movable on the bars 1 and 2. It has two indentations 9 and 10 forming sheaths into which the points fit when the clamp is closed.

The use of the slide may be seen from Figs. 4 and 6. The fabric to be fastened, 11 and 12, is fixed by each of the slides shown in Figs. 1 or 7. These two fastening devices are connected wih each other. i. e. by the elastic band 13, so that the ends 11 and 12 of the fabric (or textiles, paper fabrics and the like) are pulled towards each other. The elastic band 13 is fastened under the upbent strip 5 which may also have the shape 14 as shown in Figs. 7 and 8.

I claim:

1. In a device of the character described, a member comprising spaced parallel bars and a pair of cross-bars extending transversely of said spaced bars to interconnect the same, a slide element slidably mounted on said parallel bars for movement toward and away from one of said cross-bars, said slide element having closely spaced yieldable upper and lower portions defining a socket, and a tapered prong projecting from said one cross-bar toward said socket and adapted to be frictionally gripped between the upper and lower portions of said slide bar in response to movement of said slide bar toward said one cross-bar.

2. A combination as defined in claim 1, wherein the upper and lower portions of said slide bar are uninterruptedly connected to provide a continuous sheath encircling said member transversely of said spaced parallel bars.

3. A combination as defined in claim 1, wherein said prong and the socket-carrying portion of said slide bar are otfset in a plane parallel to the plane of said crossbars.
