Abstract
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 Analysis
Total Claims: 13
Claim 1
Independent Claim
75 words
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.
Claim 2
Dependent Claim
75 words
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.
Claim 3
Dependent Claim
20 words
Watch band according to claim 1 wherein said strap is secured to the outside of said tubular element (FIGS. 1-4).
Claim 4
Dependent Claim
23 words
Watch band according to claim 1 wherein said tubular element (4) consists of thermoplastic material, said strap being bonded to said thermoplastic material.
Claim 5
Dependent Claim
24 words
Watch band according to claim 1 wherein said strap (5) is secured to the tubular element at an edge (12) of the slit (6).
Claim 6
Dependent Claim
45 words
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.
Claim 7
Dependent Claim
16 words
Watch band according to claim 5 wherein both said layers are secured to said tubular element.
Claim 8
Dependent Claim
55 words
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).
Claim 9
Dependent Claim
18 words
Watch band according to claim 7, wherein said bottom layer is movable with respect to said tubular element.
Claim 10
Dependent Claim
34 words
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.
Claim 11
Dependent Claim
26 words
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).
Claim 12
Dependent Claim
31 words
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.
Claim 13
Dependent Claim
21 words
Watch band according to claim 1 including a projection (16) formed on the tubular element in the region of the slit.
