1. A portable anti-theft device for vehicles having a steering wheel which includes a rim to which the device can be locked with a part thereof projecting therefrom to limit the free angle of rotatability of the steering wheel relative to the internal structures of the vehicle to thereby limit the drivability of the vehicle, the device comprising:

  • a bar having first and second opposite ends and a steering wheel rim clamping section located therebetween which has a dimension greater than the diameter of a steering wheel rim, the clamping section including first and second clamping members pivotally interconnected by a hinge having an axis parallel to the bar, the clamping members being pivotal to a closed position in which they surround and clamp to a section of the rim to thereby rigidly support the device on the rim with the bar tangent to, and with at least one of the ends displaced tangentially from, the section of the rim to which the clamping members are clamped, the clamping members being pivotal to an open position in which the device may be positioned on and removed from the rim; and

    means on said bar for locking the clamping members together in the closed position to thereby limit the rotatability of the steering wheel and the drivability of the vehicle.
