Abstract: An electrically-controlled locking arrangement for a lock mechanism of a commercial vehicle load space door includes a housing and a hook member rotatably mounted within the housing for engagement with an external catch member. A handle is coupled to the hook member to effect movement between open and closed positions. A detent is provided either on the hook member itself or on a component coupled to the hook member, a locking dog being arranged for movement between a locked setting where the dog is in engagement with the detent and a free setting where the dog is clear of the detent, to allow operation of the handle to move the hook member to its open position. An electric actuator is mounted within the housing to drive the locking dog to its free setting allowing rotation of the hook member from its closed position to its open position.
