Abstract: The invention relates to a decorative article with a system (7) for interlocking two portions (5, 6) of at least one part (3, 4), comprising a screw (8) and nut (9) assembly which passes through each portion (5, 6) and is intended to press the two portions (5, 6) against each other by screwing. According to the invention, the interlocking system (7) comprises a flexible safety device (13) so that the screw (8) and nut (9) assembly can continue to be screwed and unscrewed whilst elastically preventing relative displacement between the screw (8) and the nut (9) below a predetermined torque.

Abstract: The invention concerns a bracelet link suitable for forming a bracelet, the main direction of which defines a longitudinal axis, said link comprising: —a body passed through by a channel arranged in a direction transverse to the longitudinal axis, said channel being interrupted by a link portion provided in said body, in which a second link can engage, —a bar housed in the channel, said bar being capable of being moved in translation in the channel with respect to the body, between an assembled position in which the bar passes through the link portion and a free position in which it leaves the link portion free, —a locking member arranged so as to be movable in translation between a first position in which it locks the longitudinal position of the bar in order to hold it in the assembled position of same, and a second position in which the bar is movable in translation, and—an elastic member applying a force to the locking member that tends to hold it in the first position of same.
