Lock assembly for anti-theft device for vehicle

A lock assembly for an anti-theft device for a vehicle comprising a lock body including a base for engaging with a pair of shanks, said base having four planar side surfaces and a flat planar upper surface thereby forming a rectangular-shaped solid, at least two depressions formed on top of said base, a box secured on top of said lock body and including an orifice formed therein for receiving a core, said box comprising a substantially rectangular-shaped solid, smaller than said base, and having four side surfaces perpendicular to the upper surface of the base and a flat upper surface that is parallel to the upper surface of the base, the box being secured to the upper surface of the base leaving portions of the upper surface of the base exposed on either side of the box, said orifice having a substantially cylindrical shape, its axis being perpendicular to the upper surface of the box, said base having a depression on the exposed portion of the upper surface of the base on either side of the box, a casing engaged on said box and including at least two ears engaged in said depressions of said base, said casing having four sides and an upper surface perpendicular to the sides thereby forming a generally rectangular-shaped solid that is open on the bottom, defining an inner hollow portion, configured to closely enclose the exposed surfaces of said box in a nesting relation when placed over the box, said ears being on opposite sides of the casing and extending perpendicularly outward from the sides and parallel to the upper surface of the base, a housing including two flanges having a slot formed therebetween for engaging with said casing, said flanges engaging with said ears so as to retain said ears within said depressions, said housing comprising a substantially rectangular prism open on both ends and having a slot on the upper surface connecting the open ends to allow the housing, to be slid over the assembled base, the slot being substantially the same width as the casing but not as wide as the base thereby defining flanges parallel and on either side of the slot, thereby allowing the box, and casing to protrude through the slot with said flanges covering the exposed portions of the upper surface of the base on either side of the box and retaining the ears in the depressions, thereby encasing and retaining the base, box, and casing in a nesting relationship, and a covering engaged on said casing and said housing for retaining said lock body in said housing.
