A self-releasing hook comprising the following basic elements: a hook body having a slot to receive a load ring or the like and a crotch in which the load ring rests when loaded, a plunger for raising the load ring out of the crotch in the hook body, a latch for holding the loaded hook ring within the slot at least prior to loading, a spring for urging the plunger to the ejection position and another spring biasing the latch in a position blocking exit from the slot. The slot is shaped to receive the load ring and permit the latch to return to a latching position while the plunger is in the ejecting position.
