Abstract: A diametric style steering wheel lock is disclosed having improved strength and resistance to forced removal, while, at the same time, demonstrating increased ease in actual use. The steering wheel lock utilizes an enclosed and protected dead bolt locking system providing positive and powerful diametric fixation of the device across a vehicle steering wheel. Although dead bolt operation is employed, the device demonstrates free rotation of one or both steering wheel rim engagement means facilitating placement of the device. In addition, the steering wheel lock advantageously incorporates longitudinally aligned adjustment and locking grooves located upon the surface of the locking rod to provide quick, keyless application of the lock including, extension, contraction and rotation further facilitating positioning thereof. Push-to-engage means as well as automatic dead bolt engagement is disclosed in the disclosed embodiments.
