Abstract
Bracelet clasp (1) with a buckle (10) having strands carrying shouldered pins (6, 7) cooperating with eyes (8, 9) in the buckle, with two pushers (11, 12) antagonistic against springs, each controlling two bolts (15, 16; 17, 18), where the first pusher (11) integrally drives a first bolt (15) opposite a first pin (6) and a second bolt (16) opposite a second pin (7), this first pin (6) and a second bolt (18) opposite this second pin (7), so that only the combined actuation of the two pushers (11, 12) drives all of the bolts (15, 16, 17, 18) through their entire release travel to release these pins (6, 7) and one of the bolts (17, 18) remains locked during insertion of a pin (6, 7) in an eye (8, 9).
