     Referring to FIGS. 1-81, wherein like numerals indicate like elements throughout, there are shown preferred embodiments of an anti-theft device according to the present invention. Briefly stated, the anti-theft device is attached to a vehicle  10  to limit the motion of a steering wheel  12  to deter theft of the vehicle  10 . 
     It is preferred that the anti-theft device, and its individual components, be formed of a high strength, durable, impact resistant material, such as stainless steel. Those or ordinary skill in the art would appreciate that any other suitable steels, alloys or the like that are suitable for use with anti-theft devices can be used without departing from of the present invention. Preferably, an outer surface of the anti-theft device is coated with a brightly colored paint or coating, such as a fluorescent orange colored paint or vinyl coating, so that the anti-theft device is prominently visible and noticeable when installed on the vehicle  10 . 
     Referring to FIGS. 1-7, one embodiment of the anti-theft device for vehicle is adapted to detachably engage the steering wheel  12  which is rotatable mounted on a steering column  14 . The steering wheel  12  has a rim  16  defining an outer perimeter of the steering wheel  12 . The rim of the steering wheel can be irregularly shaped without departing from the scope of the present invention. 
     The vehicle anti-theft device includes an elongated member  18  having a first end  20  and a longitudinal surface  22 . The elongated member  18  is adapted to be located proximate to the steering column  14 . Referring briefly to FIGS.  31  and  61 - 63  the elongated member can have a cross sectional shape of any one of a square, a rectangle, a circle, an ellipse, a polygon or the like without departing from the present invention. Additionally, the elongated member  18  can be an elongated ring (as shown in FIGS. 61-63) without departing from the scope of the present invention. Referring still to FIGS. 1-7, the first end  20  of the elongated member  18  preferably extends generally radially outwardly away from the steering column  14  past the outer perimeter of the steering wheel  12 . It is preferable that the elongated member be adapted to be located on a portion of the steering column with the elongated member being generally, but not necessarily, perpendicular to a central axis of this steering column  14 . When installed the elongated member  18  can be positioned at the joint between the steering wheel  12  and the steering column  14  (as shown in FIG. 3) to substantially surround the end of the steering column  14 . Alternatively, the elongated member  18  can be positioned over a central portion of the steering column (as shown in FIG. 4) without departing from the present invention.
