<p>The invention concerns a clasp with unfolding buckle for bracelet. It comprises two bent branches (1, 2) articulated by their ends to an intermediate link (3). When one of the branches (1, 2) is folded down on the other it can take up two different longitudinal positions, one wherein the link (3) is in the extension of one of the branches and another position wherein the link is in the extension of the other branch, locking means ensuring the relative positions of the two branches. The link (3) comprises a planar surface while its opposite surface is concave.</p> |
