Ww2 push gate snap hook

This item is a type of snap hook or clasp used for attaching straps to bags, keychains, and other accessories. It is commonly referred to by several names, including:
Oval snap hook or oval swivel hook: These terms are widely used in descriptions of handbag and leathercraft hardware.
Push gate snap hook: This refers to the mechanism for opening the hook by pushing the small internal bar or "gate".
Lobster claw clasp/hook: Although the shape is different from a typical lobster claw, this is a common commercial term for snap hooks with a similar trigger mechanism.
Pistol belt hardware or garter clasp: It appears visually similar to some vintage or military hardware components, such as those found on WWII US pistol belts or garter belts, as identified in historical or cosplay discussions.
The item has an antique brass or similar finish. The small, movable piece is a spring-loaded "gate" which, when pushed, allows the hook to connect or disconnect from a ring or loop.
