Title: Locking device

Abstract: An anti-theft lock arrangement for a motor vehicle comprises a lock mechanism that normally disables the motor vehicle and a timing mechanism, actuated when the ignition switch is switched to a first position, for transmitting a lock release signal to unlock the locking device after a predetermined time interval from the instant of actuation of the timing mechanism, the locking mechanism being unlocked only when the lock release signal is applied thereto and the ignition switch is switched to a second position after the time interval and during the duration of the lock release signal, neither the predetermined time interval nor the lock release signal being capable of being sensibly perceived.
