ABSTRACT:
A safety armature for a cylinder having a key aperture or keyway, comprises a safety element which is in the form of a magnetically encodeable closure which can be opened by a magnetically coded disk and, which, in its locked position, covers the key aperture or keyway. The magnetically codeable closure may either be a magnetically encodeable padlock having a steel shackle which is held between guide disks of a guide element on the safety armature, or a solidly mounted mounting with a slide unit which is movable on the mounting and that can be latched by means of the magnetically encodeable enclosure.
