PROBLEM TO BE SOLVED: To provide a detachable locking device which is improved in crime preventive performance because it takes a considerable period of time for an outsider to detect a key code thereof, allows the strict control of an object to be locked as appropriate due to the arbitrary change of the key code, and contributes to reduction in a facility cost. SOLUTION: A case body of the detachable locking device abutted on a cover has a fixed-side locking arm, a movable-side locking arm, a code matching locking mechanism, and a lock lever mounted therein. The lock lever has a locking portion formed thereon which disengageably engages with a bearing hole formed in the movable-side locking arm when the lock lever is operated for luffing rotation. When codes of a plurality of dial disks match with preset unlocking code rows, a lock plate assumes an unlocking position. At this time, the lock plate is detached from the lock lever, and therefore the luffing rotation of the lock lever is allowed which leads to the detachment of the movable-side locking arm from a recessing part of a casing.
