A number of embodiments of wheel locks for vehicle wheels having an opening are disclosed. In each embodiment, the lock includes a plurality of pivotally connected elongated members having end members that are provided with a locking means for locking them together. As a result, the lock can be inserted through the wheel and around a fixed object and locked like a chain. Various embodiments are disclosed for protecting the pivot pins of the pivotal connections from attack and for restraining the pivotal movement of the elongated members. In some embodiments, the pivotal movement is restrained by placing a frictional drag on the components so that the elements cannot freely pivot. In other embodiments the degree of pivotal movement in one direction is limited more than in another direction so that the lock can only be installed in the correct relationship.
