Abstract
A snap-hook, including a hook and a dual-direction latch pivotally attached to the hook by a latch pin. The dual-direction latch blocks an opening to the hook's throat when held in a neutral position by a latch spring having a first spring force and a lever-return spring having a second spring force. The dual-direction latch is configured to move into the throat by overcoming the first spring force and to move out of the throat by overcoming the second spring force. The dual-direction latch comprises a spring guard attached to the dual-direction latch so as to shield the lever-return spring from coming into contact with one or both of an object disposed within a throat of the hook and an inner edge of the hook throat.
