What is provided is a closing device for a door, which has additional locking devices which are remote from the door lock and which are locked automatically during the closing of the door lock and are unlocked again within a predetermined period of time as a result of a multiple to-and-fro movement of the lock bolt over at least two closing operations. For this, the lock bolt (218) interacts with a position transmitter (272, 274) which is arranged in the lock plate (238) and which supplies different output signals in the two end positions of the locked bolt. These are checked in a correlation device (268) as to whether they succeed one another within a predetermined period of time, within which the movement of the lock bolt can occur only as a result of the proper actuation of the lock by the associated key. Drives (260, 262) assigned to the bolts of the additional locking devices are activated by the correlation device (268). <IMAGE>
