<p>The unfoldable clasp for a bracelet comprises a central shaft (1) formed from two parallel longitudinal members (2, 3) which are connected at their ends (4, 5), where unfoldable arms (6, 7), folding over and locking in the shaft (1) over a member (81, 82, respectively), transversely connecting the two longitudinal members (2, 3), are articulated. Each arm (6, 7) comprises a head (9, 10) which both receives a strand of the bracelet and ensures locking of the arm inside the shaft, and these heads (9, 10) each have, on their front face, a concavity (13, 14) which, upon locking, bears in compression on the transverse member (81, 82) and thus immobilises the unfoldable arm. The locking heads (9, 10) each have on their lower face (15, 16), a transverse groove (17, 18) placed to the rear of the concavity (13, 14). <IMAGE></p> |
