2001	Invention patented by Jean-Marc Deriaz, Luigi Ferrario, and Daniel Moille on October 21th, 2001. Abstract: A bracelet clasp having two branches (1, 2) which are articulated to one another by a respective first one of their ends in order to make it possible to fold a first one of these branches over and/or into the second of said branches, and to unfold it in order to place it substantially in the extension of this second branch, while their respective second ends are intended to be connected to two ends of a bracelet. These two branches (1, 2) include mutual attaching structures (4, 10) for holding them in the folded position. The second end of the first articulated branch (1) includes linking structure (9) having parallel axes of articulation, one for connecting these linking structures to this first articulated branch (1) and at least a second one for connecting these linking structures (9) firstly to one end of the bracelet and secondly to an actuating member (18) for exerting a force capable of separating said mutual attaching structures (4, 10).
