Subject device includes a pair of companionate arcuate arms which (when locked) circumferentially embrace the wheel with one of the arms being movable to an open position to facilitate initial engagement with the wheel. A chassis-strikable lock-bar is fixedly attached to the arcuate arms for making forceable contact with the frame structure of the vehicle as a result of any movement thereof. Thus, the lockbar impedes any significant movement of the vehicle, i.e., whether it be inadvertent or unwarranted. A typical padlock locks the arms together in their closed position and an encasement closely envelopes the padlock shielding it against unwarranted abuse and destruction.
