Abstract
An improved means is disclosed for detachably retaining the link of a chain to be temporarily engaged by a chain-grappling 'claw' type hook. The retaining means comprises a resilient member at least partially over-reaching the 'pocket' portion of the hook into which the link of the engaged chain is temporarily captured; and is so constructed and arranged as to release the engaged chain link only when intended by the user, and with improved facility and ease of operation by the user.
