Abstract: A clasp for a wristlet has at least two movable blades (4), (5) articulated with respect to one another about an axis of the blades (51) and a locking device (10) making it possible to lock or unlock a first blade (5) relative to a second blade (4), respectively in closed and open configurations of the clasp. The locking device (10) is linked to the first blade (5) and has an actuation lever (2) intended for the actuation of the locking device by a user, a locking element (1) capable of cooperating with a complementary locking element (4a) of the second blade (4), and an intermediate element (3) linked to the locking element (1) by a first link device and to the actuation lever (2) by a second link device, at least one of these two link devices being provided with at least two degrees of freedom.

Abstract: An adjustment device (100; 100?; 100?) for adjusting the length of a bracelet, having at least one adjustment assembly (10; 10?; 10?) movable relative to a clasp cover (7; 7?; 7?), the adjustment assembly and the cover being respectively provided with a first and a second fixing element (11, 71; 11?, 71?; 11?, 71?) for their respective fixing according to several positions capable of inducing different bracelet lengths, and also being provided respectively with a first and a second indexing element (21, 72; 21?, 72?; 21?, 72?) for their temporary respective positioning according to one of the several positions, the adjustment assembly (10; 10?; 10?) also comprising a guiding device including a first guiding element (3, 4, 5; 3?, 4?, 5?; 3?, 4?) cooperating with a second guiding element (74; 74?; 74?) of the cover (7; 7?; 7?) to guide the displacement of the adjusting assembly (10; 10?; 10?) relative to the cover (7; 7?; 7?), the first indexing element (21; 21?; 21?) being independent of and/or distinct from t
