PCT No. PCT/CH96/00096 Sec. 371 Date Mar. 18, 1998 Sec. 102(e) Date Mar. 18, 1998 PCT Filed Mar. 14, 1996 PCT Pub. No. WO96/31138 PCT Pub. Date Oct. 10, 1996A clasp fastener having a clasp (1) is designed to be snapped into engagement by exerting a closing force. A locking device (4) for locking the clasp (1) is placed by the closing force in an engaged position in which it is in a first snap engagement with a locking projection (6), and a closing member (5) for closing the clasp (1) is fixed by the closing force in a safety position in which it is in a second snap engagement with the locking device (4) so that the snapping force of the first engagement of the clasp (1) with the locking projection (6) is increased. At least one variable-diameter pin (17,18) that is flexible and/or has different diameters allows some movement of the locking device (4), so that the effective closing force exerted on the locking projection (6) is reduced. |
