Abstract : An actuating rod is locked firmly in position by a split spring locking ring which engages matching shoulders in a groove on the rod. An electrical signal operates to energize a squib gas generator which produces pressure forcing a piston inward unlocking the ring and engaging wedge faces on the split locking ring causing the ring to spread open and release the actuating rod which moves upward in response to the forces of an extension spring. When locked, the rod has great resistance to imposed axial and side loads.
