A jewelry clasp having a pair of bodies at the free ends of a piece of jewelry affixed together by magnetic forces. Each body has a magnet means having north and south poles that are aligned along the longitudinal center line of the clasp with opposite poles abutting each other to hold those bodies in the affixed relationship. There is a safety catch on one of the bodies having a protrusion extending therefrom that overlaps the other body to hold the bodies together. As the protrusion is moved into its latched position, the other body is displaced along the longitudinal centerline to misalign the respective magnetic means, and when the protrusion seats in its latched position, the magnetic means realigns by the magnetic attraction between the magnetic means creating an click that can be heard and/or felt by the wearer to confirm that the bodies are properly affixed together.

The linked bracelet, in particular for a watch, comprises a metal hinged chain passing through a series of ornamental tubular links (4) made of ceramic material, each ornamental link (4) having at least one longitudinal passage (20), in which a metal link and a hinge associated with it are housed and can rest against an inside surface (26) of the base (27) of the ornamental link in the region of the hinge, when the hinge is in a folded position. A front face (23) of each ornamental link (4) has at least one raised section (34) located in the same region of the width of the ornamental link as said inside surface (26) where the hinge or the metal link rests, this raised section being arranged to abut against the opposite front face (24) of the adjacent ornamental link when the hinge is in said folded position. This arrangement balances the vertical force (F) exerted by the chain on the base (27) of the ornamental link at the right place and thus prevents any risk of fracture by transverse bending.
