Abstract
Abstract In a steering column locking device a further protective mechanism for said locking device composed of an enclosure composed of two substantially semi-circular side walls, structurally hinged by concealed hinges at each of one extreme, a pair of open chambers forming a part of the other extremities of the side walls, the chambers being slidable one within the other. A cylindrical lock mechanism is carried by one open chamber and is keyed to operate a slug depending from the lock so that the slug engages an aperture in the other chamber thereby locking the two semi-circular walls about the steering column locking device.
