The present invention relates to a lock (1), of the type comprising: a peripheral cylinder (10) comprising a longitudinal cavity (10A); an internal cylinder (20) at least partially housed in said longitudinal cavity (10A), said internal cylinder (20) being provided with a longitudinal recess (20A) for inserting a key (2), wherein the peripheral cylinder (10) comprises a plurality of first channels (11) arranged radially and substantially aligned with respective second channels (21) of the internal cylinder (20) when the lock (1) is in a locked configuration, said first channels (11) and second channels (21) being adapted to slideably house retaining means (30) adapted to exert a retaining action between the internal cylinder (20) and the peripheral cylinder (10) when the key (2) is not housed in said longitudinal recess (20A). The invention is characterized in that the internal cylinder (20) is fixedly mounted in the lock (1), and the peripheral cylinder (10) is mounted in said lock (1) in such a way that it can be rotated about at least a portion of the internal cylinder (20) following the insertion of the key (2) into the longitudinal recess (20A) of the internal cylinder (20) and the release of the retaining means (30). |
