ABSTRACT:
A safety hook construction is operable for providing a simple, safe and durable interconnection between a safety belt, harness, etc., and a safety line. The safety hook comprises a hook body, a closure member pivotally mounted on the body and normally biased to a closed position wherein a mouth portion of the hook body is obstructed, and a latch mounted on the closure member which is normally biased to a locked position which prevents opening of the closure member. The safety hook is preferably formed so that the latch is pivotally mounted on the closure member and normally biased so as to engage a locking shoulder formed on the edge of the body opposite the mouth to prevent opening of the closure member. Accordingly, the hook can be operated with one hand, i.e., by placing it in the palm of the hand, depressing the latch with the thumb to effect disengagement from the locking shoulder, and thereafter moving the latch toward the palm of the hand with the thumb to simultaneously swing the closure member to its open position.
