Abstract: A security device for immobilizing a vehicle by securing one or more of its wheels to a fixed location. The device includes an anchorage assembly mounted on a flat horizontal surface that includes two spaced apart channels and one stopper member near to one of the channels. A central assembly with three walls, perpendicularly mounted to each other, is slidably mounted to the anchorage assembly. A holding assembly removably locks central and holding assemblies together. The central assembly has several arms that extend radially outwardly and embrace a vehicle's wheel. A reinforcing arched member connects the bent portions of the arms enhancing the structural integrity of the holding assembly.
