Abstract: An improved jewelry catch comprising a folded pin adapted to be received within a rectangular box for releasable, locking engagement therewith for stringing jewelry on a jewelry chain and securing opposite ends of the jewelry chain. The folded portion of the pin includes a resilient, angle tab which extends through an opening in the box when the pin is received therein, thereby prohibiting rotation of the pin within the box and unintentional disengagement of the pin therefrom. The shape of the pin and box and the size tolerances therebetween further impede the rotation of the pin within the box and the unintentional disengagement of the pin therefrom. The pin may be readily disengaged from the box for the purpose of threading the pin through a minute hollow passage in a piece of jewelry by manually deflecting the tab through the box opening and pulling the pin outward from within the box.
