The invention concerns a releasable lock ( 10 ), in particular for a motor vehicle locking system, comprising a fixed stator ( 14 ), an intermediate tubular sleeve ( 16 ) which is mounted rotating about its axis in the stator and which is axially fixed relative to the stator, a rotor ( 12 ) which is mounted rotating inside the sleeve, which is axially fixed relative to the sleeve and which comprises springs ( 32 ) radially mobile under the action of a key designed to be axially introduced into the rotor, the rotor ( 12 ) and the intermediate sleeve ( 16 ) being locked in rotation relative to each other by the springs when the key is not compatible, a driving element ( 26 ) coupling the rotor and a control lever ( 24 ), called flat latch, when the key is compatible and an indexer ( 28 ) which is axially mobile between a rest position and a releasing position, under the effect of a rotation of the sleeve relative to the stator following the rotation of the rotator by means of a non-compatible key, to move the driving element axially towards a released position. The invention is characterized in that the indexer ( 28 ) and the driving element ( 26 ) are cylindrical parts enclosing the rotor ( 12 ) and are nested mobile into each other, the driving element ( 26 ) is linked in translation on the rotor ( 12 ) and the indexer ( 28 ) is linked in translation in the stator ( 14 ).
