A disc tumbler lock, which comprises a lock case (1), which includes a bolt (3) displaceable with a key of the lock and a number of locking discs (13) provided with locking channels (17) and which are displaceable with the key of the lock against the force of a spring (14) to open the lock and for guiding the movements of which the lock case is provided with stationary guiding members (8,9), and a locking pin (12) dependent on the movements of the bolt and which is arranged to cooperate with the locking channels (17) of the locking discs. At least one of the locking discs (13) is equipped with gripping means (18), which, when the bolt (3) is pressed inwards to the lock case are arranged to cooperate with counter means (19) arranged in the lock case for preventing the displacement of the said at least one locking disc (13). Further, the said at least one locking disc (13) is spring-loaded to turn the locking disc around a first guiding member (8) against a second guiding members (9) so that the said second guiding member (9) guides the said at least one locking disc (13) substantially towards the head of the bolt (3) to be protruded out from the lock case.

Une des clavettes de verrouillage (13), au moins, est dotée de moyens de retenue (18), qui, lorsque le pêne (3) est pressé vers l'intérieur du boîtier de serrure, sont disposés afin de coopérer avec des moyens complémentaires (19) agencés dans le boîtier afin d'empêcher le déplacement de la clavette (13). En outre, cette clavette (13) est armée par un ressort afin de tourner autour d'un premier élément guide (8) contre un second éléments guide (9) de façon que le second élément guide (9) amène la clavette (13) sensiblement vers la tête du pêne (3) de façon à le faire sortir du boîtier de serrure.
