Design

The device consists of two pieces which, when locked together, form one long, fixed bar with two protruding hooks opening towards the ends of the bar. Each piece has one hook, intended to fit around the rim of the steering wheel. The smaller of the two pieces fits inside the larger piece and slides in and out for sizing. When the lock is set, the larger piece's long handle protrudes out, so that the wheel is practically impossible to turn due to collision with other parts of the car or with the driver's legs, and the device cannot be removed because it is too large to slip around the wheel. To remove the device, the user unlocks the central bar, and slides the pieces together so that the hooks no longer surround the rim of the wheel; this allows it to slip out, freeing the wheel.

Weaknesses

The Club as originally designed was prone to having its lock shattered by freezing with freon; later models addressed this issue by changing to a chromium

 broadcast test showed that this form of attack now took several minutes of hammering. The most grievous flaw in the design is inherent in the modern construction of steering wheels; thieves can defeat this type of lock by cutting away part of the steering wheel's rim, allowing the device to be removed. This does, however, require access to a hacksaw

Recently, a device called "The Buster" has been designed for locksmiths. It is a big screw with a hook on one end and a large handle on the other and two legs designed to rest on the lock. It breaks steering wheel locks such as the Club by hooking onto the lock and tightening the screw with the handle. The large handle provides mechanical advantage
