A locking assembly for preventing the unauthorized insertion of an object into, for example, a video cassette recorder through an opening in the recorder with the assembly including a housing having an exterior structure closely corresponding to the opening provided in the recorder and defining an interior space. The assembly further includes a locking mechanism disposed within the interior of the housing and supported by the housing for locking the assembly with respect to the recorder. A stop means is moveable between extended and retracted positions for providing locking contact with the recorder and preventing the removal of the assembly when the stop means is in its extended position. The assembly also includes a lock member which is operable from the exterior of the housing for operatively moving the stop member between the extended and retracted positions. A crank mechanism is operatively connected to the stop member and to the lock member and is rotatable between first and second positions. The crank mechanism includes a crank member having at least one connecting rod operatively connected to the stop means and the crank member for moving the stop member between the retracted and extended positions.
