ABSTRACT:
The present invention features a user-friendly locking snap-hook having an inwardly acting release mechanism that requires the simultaneous depression of interacting grips. Each of the gripping surfaces of these grips is usually flush or slightly recessed with the hook surface periphery, so as to prevent snagging or accidental damage during usage. The keeper member of the hook apparatus functions in a dual-purpose capacity. It forms the eye of the hook loop, and it functions as one of the grip members of the release mechanism. The keeper member opens inwardly, so that it will not afford the opportunity for it to become snagged or damaged during usage. The grip members each pivot inwardly into the safety hook body. The advantage of providing an internally locking mechanism, as opposed to the conventional external type of device, is that the user can avoid damaging his other safety equipment as well as the snap-hook mechanism itself.
