Abstract

A tubular element of elastic temporarily deformable, preferably thermoplastic material is bonded to the watch strap, for example by fusion if the watch strap is likewise of plastic material; the tubular element has a transverse slit so that, upon deformation of the tubular element in the region of the slit, the cross pin of a wrist watch case can be snapped through the slit into the hollow of the tube.

Claims

1. A watch band having a strap (1,2) formed with an end terminal for connection to the cross pin (14) of a wrist watch casing, comprising:

a tubular element (4) secured to said strap, said tubular element being of elastically deformable material and formed with a longitudinal slit (6), the elasticity of said material being sufficient to permit temporary deformation of said tubular element to enable said element to be snapped over the watch case pin.

2. Watch band according to claim 1 wherein said strap is secured to the outside of said tubular element (FIGS. 1-4).

3. Watch band according to claim 1 wherein said tubular element (4) consists of thermoplastic material, said strap being bonded to said thermoplastic material.

4. Watch band according to claim 1 wherein said strap (5) is secured to the tubular element at an edge (12) of the slit (6).

5. Watch band according to claim 1 wherein said strap is formed with two layers, said tubular elements being positioned relative to said strap such that a plane (7) passing through the slit and the center of the tubular element is approximately parallel to said strap.

6. Watch band according to claim 5 wherein both said layers are secured to said tubular element.

7. Watch band according to claim 1, wherein said strap is formed of a top layer and a bottom layer (6) said top layer being secured to said tubular element and said bottom layer having a portion located in the interior of said element, passing through said slit (6) and surrounding (15) the cross pin (14).

8. Watch band according to claim 7, wherein said bottom layer is movable with respect to said tubular element.

9. Watch band according to claim 1 wherein said strap is formed of two layers and a third reenforcing layer (8) interposed between said two layers, said reenforcing layer being secured to said tubular element.

10. Watch band according to claim 9 wherein said reenforcing layer is of textile material and secured to said tubular element along a transverse, weft thread (9).

11. Watch band according to claim 9 wherein said reenforcing layer is of textile material and secured to said tubular element at crossover points (11) of weft (9) and warp (10) thread.

12. Watch band according to claim 1 including a projection (16) formed on the tubular element in the region of the slit.
