A safety lock, particularly a self-locking lock, including at least one l catch and a bolt operable by a lock cylinder and a split latch nut. For creating a particularly inexpensively manufacturable and relatively narrow safety lock, a coupling device of the lock is provided with two congruent racks which have a panic or freewheel function. The racks are superimposed and mesh with the teeth of the inner and outer nut. An electromagnetic coupling is achieved with the aid of a coupling lever, which is fixable to each rack directly or indirectly subjects to the function of the particular rack and engageable with a detent of the racks.
