Abstract
Abstract The device is so arranged that while it may allow a limited movement to a wheel it prevents the wheel being turned through more than fraction of a full turn and thus would prevent a vehicle being driven away or a machine or appliance being turned on, or a boat being steered unauthorised. The device comprises a boss plate (25), two pivoted callipers (29) which wrap around the vehicle wheel and an adjustable calliper (27). Stops (28) limit movement of the pivoted callipers (29). Calliper (27) slides in bracket (26) and can be locked in a number of different positions by a padlock (31) engageable in holes (28). Extension (27b) will engage the ground or part of the vehicle and prevent unauthorised movement.
