An adjustable link for bracelets, including a first half link and a second half link arranged to be assembled to move with respect to each other, including an adjustment, and a locking mechanism cooperating with a complementary locking mechanism in order to form a captive assembly. The adjustment includes a screw, a hole passing through the first half link, and a blind threaded hole extending into the second half link, the through hole and the blind threaded hole facing each other, and being arranged to cooperate with the screw to continuously adjust the position of the first half link and of the second half link in the longitudinal direction in order to adjust the position between a maximum position and a minimum position.

A connector for a ball chain includes an arcuate bottom portion having a longitudinal centerline axis extending from a first end to a second end, a first ear extending from the arcuate bottom portion and inward towards the longitudinal centerline axis, and a second ear extending from the arcuate bottom portion, opposite the first ear laterally across the longitudinal centerline axis. The connector having a plurality of configurations, a first being an unsecured configuration, in which the first ear extends from the arcuate bottom portion inward towards the longitudinal centerline axis and the second ear extends from the arcuate bottom portion substantially perpendicular to the longitudinal centerline axis, and a second being a secured configuration, in which the second ear is folded inward towards the first ear and the longitudinal centerline axis in order to overlap the first ear and to secure a ball of the ball chain.
