Abstract
An extensible clasp is described for use with a watch strap of flat flexible material having at one end a portion formed with a loop fitted with a buckle and at the other end a portion providing apertures for the tongue of the buckle. The clasp comprises first and second elongated portions that are connected by a hinge pin. The outer end of the first elongated portion is pivotally mounted on one of two pins of a link element, the other pin being fitted in said loop after removal of the buckle. The second elongated portion consists of a flattened sleeve into which the apertured end portion of the strap is inserted and secured by a screw. The strap thus becomes continuous and is unlikely to slip off when being fitted round a wrist. To close the clasp, the two elongated portions are folded against each other and a hole near the outer end of the first elongated portion is pressed into locking engagement with a beak element on the second elongated portion. The first elongated portion is resilient and so curved and the hole and beak element are so positioned as to produce a snapping engagement.
