ABSTRACT:
An apparatus for connecting a lifting mechanism to a load, the apparatus comprising a hollow annular body having a radial slot extending from the periphery of the body inwardly toward a central aperture. An arcuate bolt is operatively movable within the cavity of the body between a closed position wherein the bolt traverses the slot and thereby engages the load and an open position wherein the bolt is clear of the slot and, thus, disengaged from the load. At least one connector link and an actuating link lock the bolt in the closed position until the actuating link is operated on by a release mechanism.
