ABSTRACT:
Disclosed is a locking device which comprises a stationary member permanently mounted on a door structure together with a passive stationary block permanently mounted on adjacent wall structures which is connected to an interlocking member by means of an armored cable, the interlocking member interlocking with the stationary member to preclude movement in all directions but one and with a cylindrical barrel lock interlocking with both the stationary member and the interlocking member to preclude movement in the remaining one direction. The entire structure is generally invulnerable to attack by conventional burglary tools unless such attack is carried out for excessive periods of time, e.g., an hour or longer.
