ABSTRACT:
A device is provided for use in releasably securing one unit (e.g., the rear end of a truck vehicle) against a second unit (e.g., a loading dock). The device comprises an elongated member mounted for controlled endwise movement relative to a locking assembly, the latter being adjustably mounted on the loading dock. Carried by the elongated member and extending from an end thereof towards the truck is an attaching means which is secured to the truck. A friction means is adjustably mounted within the locking assembly for movement between operative and inoperative positions. When in an operative position, the elongated member can be moved endwise in only one direction away from the truck. When in an inoperative position, the elongated member can be moved in either endwise direction relative to the locking assembly. The friction means is biased to normally assume an operative position. Manually actuated means is carried on the locking assembly for moving the friction means from an operative position to an inoperative position.
