Coupling device for coupling a strap to a wrist-watch.

摘要

A slit pipe (4) which is compressible in a radial direction thereof is attached to a watch case between a pair of leg portions (1a). A groove (5a) is formed in a link (5) of a watch band (2) so as to be engaged with the slit pipe (4). The groove (5a) has an opening (5b) formed on the underside of the link (5), an introducing portion (5e) communicating with the opening (5b), a groove (5c) portion formed at an innermost end of the groove (5a). The opening (5b) has a width smaller than an outer diameter of the pipe (4), and larger than an outer diameter of the pipe (4) when compressed. The groove portion (5c) has an inner diameter larger than the outer diameter of the pipe (4). Thus, the pipe (4) may be inserted in the groove portion (5c) from the opening (5b) passing through the introducing portion (5e). <IMAGE>
