ABSTRACT:
A locking assembly used to deny access to a nut or to a bolt head to prevent theft of an article that is bolted to a body such as a vehicle. The locking assembly includes a retainer through which the bolt passes and that partially surrounds the nut or bolt head that secures the retainer to the body. The retainer includes a groove that extends circumferentially around it. The locking assembly also includes a housing that fits over the retainer and that is selectively engaged to the retainer by a ball bearing that is pushed into the groove on the retainer when a key turns the shaft of a lock which turns a cam that pushes the ball bearing into the groove. The locking assembly has an exceptionally low profile, made possible by positioning the lock perpendicular to the axis of the bolt. Further strength is imparted to the locking assembly by the fact that the retainer is almost as deep in the axial direction as the housing, and the strength of the retainer reinforces the housing.
