The invention relates to a plug actuated sliding bar lock having a toothed ring (39) which surrounds the ward (43) of the plug (41) and possesses a plug insertion gap (42), and whose rotary movement via a sliding bar connection slide (53) serves for displacing the sliding bar; to obtain a functionally advantageous solution, the invention proposes that the bolt (35) be blocked in the back-locked position by a projection (65) of the sliding bar connection slide (53) and be released shortly before the beginning of the bolt shooting. <IMAGE>
