Abstract: An improved hook latch mechanism, for use with cordage loops, used for leashes, cables, ropes, rigging or like restraining devices having a center body hook with a sliding outer sleeve to cover and uncover the hook opening. A spring loaded ball locking device is employed to lock the sliding sleeve in position to cover the hook opening to thus prevent the cordage loops from slipping off the hook, depressing the ball inwardly against a spring and sliding the sleeve upwardly to uncover the hook opening, permitting the removal of the cordage loop. A swiveling bail link at the other end of hook prevents twisting of the cordage loop.
