Abstract

The device has a lock insert carrier removably fixed in a housing of a cylindrical part (4) integrated to a cover (1) for preventing access to a head (18) of a cylindrical operating axle (17). Bolt forming stems (35) are slidingly mounted in respective strikers (39) of a support frame (2) between engaging and disengaging positions, where the cover is fixed to the frame by fixation screws. An operating key is introduced in the housing for cooperating with the head so as to rotatively drive the axle and displace the stems to the disengaging position for unlocking the stems from the strikers.
