Abstract
Abstract A clasp for jewelry or the like comprising a receptor and a spring clip. The spring clip has at least one integral spring finer which is directly angularly upward and is adapted to form a locking engagement with an integral vertically downwardly directed stop member on the receptor. A release member extends transversely across the receptor and is mounted for sliding longitudinal movement within a pair of aligned horizontal slots formed in opposite sides of the receptor. The release member is movable to depress the spring finger and release it from its locking engagement with the stop member of the receptor.
