A motor vehicle accessory to be applied to a tire of a motor vehicle in order to interpose a resistance against rotation of the tire on the ground, and therefore particularly useful for protecting the vehicle against theft. The accessory comprises a pair of locking members pivotably mounted to each other at one end from an open, operable position to a closed, folded position. The ends of the locking members are formed with transversely-extending sections to extend transversely across the outer face of the vehicle tire such that when the accessory is applied in its open position to the vehicle tire, the sections engage the tire at three locations. The accessory further includes a locking device for locking the two locking members on the vehicle tire, comprising, a toothed ratchet bar carried by one locking member received within a ratchet housing carried by the other locking member.
