Abstract: An elastic hinge element for a glasses frame includes a box (100) that includes a guiding cavity (101), a slide (200) that includes a body (201) moving in the guiding cavity (101), and at least one elastic piece (204) that works with the box to produce an elastic reaction that opposes the extraction of the slide from the guiding cavity (101), in which the slide body (201) includes an inside cavity that accommodates the elastic piece. The hinge element includes a holding clip for locking a proximal end of the elastic piece relative to the box (100), with the holding clip including flexible arms that extend in a distal direction and holding element (207a) that work with the box (100).

Abstract: A folding clasp for a bracelet, including a shank comprising two parallel side members each of which have a first end and a second end, wherein the first end of one parallel side member is connected to a first end of another parallel side member and wherein the second end of one parallel side member is connected to the second end of the other parallel side member, and at least one transverse element interconnecting each of the parallel side members; a first arm having one end articulated at the first end of each of the parallel side members; and another arm articulated at the second end of each of the parallel side members, so that the first arm and the other arm are adapted fold down and lock in the shank on a transverse element, wherein each of the first arm and the other arm includes a head, having on a front face a concavity for compressing on the transverse element and on a bottom face a recess located behind the concavity, for receiving a bracelet end and for locking the arm inside the shank.
