A locking device for interlocking at least two nested shopping carts. The device comprises a housing which is attachable at a predetermined location on a shopping cart, usually but not exclusively, the handlebar thereof. A coin-activated unlocking actuator is movably mounted in the housing for limited inward displacement thereof on a working axis. A locking mechanism is also displaceably mounted inside the housing and has a locking pin and lock pin displacing member. A key element is received in a key slot provided in the housing and is immovably engaged by the lock pin. An actuator retention member engages the actuator and is comprised of one or more retention elements, one of which has a pin ejector associated therewith. The key element has in its free end at least two lock activating contact points lying in different planes for disengaging the actuator retention member to thereby release the actuator and cause the locking mechanism to engage the key element in the housing.
