The invention relates to a code-combination lock with a sensing safeguard, which is used in general as a locking body with a high degree of security. The aim of the invention is to provide a security lock which guarantees a high degree of security, can be produced at a low outlay in technological terms and is characterised by simple handling. The object of the invention is to design the locking mechanism in constructive terms in such a way as to provide a sensing safeguard, according to which, for each set code, more than one sensing for releasing the locking spindle or the secret setting is necessary for the purpose of opening the lock. The essence of the invention is that the slotted setting discs guided on the locking spindle are provided on one side or on both sides with regularly or irregularly distributed blind recesses which lie in the plane of the slot of the setting discs and which are selectively made identical and/or different in height.
