ABSTRACT:
The invention relates to a lock with interchangeable coded combinations, wherein the code is materialized by notches made in a disc. Reproduction of the exact code controls the disc so that a locking member is not displaced from its unlocking position. Furthermore, a locking member is in unlocking position only if the number of the digits of the code is respected. The invention is particularly applicable to the safeguarding of property.
