An aircraft cargo carrier restraint device that is constructed so that it cannot be accidentally moved from extended, pallet locking position to a retracted position. The device embodies locking pawls of unique design that positively preclude movement of the pawls into a retracted position unless a specific sequence of operation is followed. One of the locking pawls includes a locking notch and the other of the locking pawls includes a locking protuberance, which is closely received within the locking notch so as to positively prevent accidental downward movement of the pawls into their lowered position.
