Snap hook with locking device

摘要

The locking snap hook consists of a fixed C-shaped body (12) with one end forming a retaining element (20) and the other a pivot (16) for a pin (14) which can be locked in the closed position. The pin has a connector (22) to engage with the retaining element (20), a return spring (26), and an outer coaxial locking sleeve (18). The pin has a locking element (40) which can engage with either a hole or a notch in the sleeve to retain it in the locked or unlocked position. The locking element is in the form of a spring-loaded stud which is able to pass through the hole in the sleeve or fit into its matching notch.
