FIELD: construction.
SUBSTANCE: safety lock comprises one or more retaining plates, and also an element of variable size recoding. The recoding element contains a sequence of sizes. Each of sizes unlocks an appropriate key with one or more bits and locks each key unlocked with each previous size of sequence. Each key contains its own facility to control a recoding element arranged with the possibility of its automatic recovery to unlocking size, when a recoding element has a size preceding the unlocking size.
EFFECT: development of a safety lock with high flexibility of use, which may be recoded automatically, in a simple and quick manner.
