Telephone instruments have an apertured base through which project depressible dialing elements, such as touch tone keys or push buttons. A locking device for telephone instruments with depressible keys or buttons comprises a body fixed to the base and formed with a bore therethrough. Disposed within the bore of the body is a movable member that has one end thereof projecting over a depressible dialing element. By moving the movable member in one direction, a depressible dialing element is depressed to lock the telephone instrument. By moving the movable member in an opposite direction, the depressed dialing element under its own yieldable action rises to become fully extended to enable the telephone instrument to be operated.
