ABSTRACT:
A device for attaching a lifting cable to a load. Lifting forces are imparted through a pair of inclined surfaces of the device which surfaces engage like surfaces on the load being lifted. A main member houses positionable member which has one of the inclined surfaces thereon and may be rotated for insertion below an inclined surface on the load. The main member has the remaining lifting inclined surface thereon. A locking member is slidably mounted on a main member of the device and gravitates into a position whereat the positionable member is prevented from movement. The lifting cable passes through openings in the movable, locking and main members of the device. A bolt equipped clevis may be coupled to said members.
