This lock comprises handling members which may be actuated according to a code, and a rack which may be displaced after actuating the actuating members controlled according to the code. Each actuating member cooperates with an insertion part which comprises at least a recess and which may be brought into two different positions. The insertion parts arranged according to the code prevent, in their start position, the displacement of the rack and, in their working position given by the cooperating actuating member, they allow the displacement of the rack owing to their recess or recesses. The insertion parts, which are not arranged according to the code, operate inversely. Thus, there is no resiliency difference between the coded and non coded actuating members and it is not possible to determine the code by groping. |
