Abstract: The device covers the ignition lock which is conventionally mounted on the vehicle steering column and comprises a lock housing and a C-shaped band received by the lock housing which together cooperate to form a shroud or cover for the ignition lock. The housing has a pair of latching devices for receiving the band and locking the band relative to the housing. The latching devices are operated from a key lock which permits release of the latching devices. The housing is positioned so that the key lock faces the vehicle dashboard so that there is little space between the key receiving lock and the dashboard thereby making it difficult for an unauthorized person to "jimmy" the lock open using a prying device or the like.
