A locking device according to the present invention, for use with a trailer gooseneck, the trailer gooseneck having a post with upper and lower ends, the upper end being attached to a trailer and the lower end. The lower end forms a recess and a pair of bore holes at a right angle to the centerline of the recess for accepting a coupler for receiving a hitch. The coupler is removed to allow insertion of the locking device. The locking device includes a body adapted to fit into the recess of the lower end, a pair of locking pins within the body of the locking device, a cam within the body of the locking device and a lock to prevent the cam from being turned when the lock is engaged. The locking pins face opposite directions and are adapted to be inserted into the bore hole on the two sides of the recess. When the body is inserted into the recess and the cam is turned in one direction, the cam moves the pair of locking pins outward so that the locking pins are inserted into the bore hole, but partially remain within the body. When the cam is turned in the opposite direction, the pair of locking pins are withdrawn into the body of the locking device and the locking device can be removed from the recess. In one form, return springs engage the pair of locking pins.
