Pronunciation: [wˈiːl klˈamp] (IPA) 
A wheel clamp, also known as a boot, parking boot, or Denver boot, is a device used to immobilize a vehicle. Other synonyms for wheel clamp include parking brake, car immobilizer, and tire lock. In some regions, it is also referred to as a Barnacle, which is typically placed on the windshield of the vehicle instead of locking the wheel.

They are often seen as a deterrent against illegal parking, and in some cases, can even be used to compel payment of unpaid fines.
