ABSTRACT:
The automobile anti-theft device consists of a hardened steel collar which encircles the steering column of the automobile and includes two rotatably attached sections which are attached to each other by sliding one end of a first section underneath an end of the second section. The first section has a projection on the end which fits into a radially extending recess on the underside of the second section and thus acts as a pivot point about which the first section rotates relative to the second section. The first section consists of an arcuate body, which is shaped to cover a portion of the side of the steering column, and a projection which extends radially out from the arcuate body. When this section is in place on the steering column, the projection is thus approximately perpendicular to the steering column. The second section consists of an arcuate body which is shaped to cover a portion of the steering column which is contiguous with and on the same side as the portion covered by the first section. The second section includes on its underside a recess which is shaped to receive the projection. When the collar is assembled around the steering column, the projection is disposed underneath the second section and extends into the recess to secure these two sections together to form the collar member. One of these sections then attaches to the other collar member, such that the collar encircles the steering column.
