The present invention relates to a security locking system of the type comprising a cylinder (3) provided with a set of pistons (8) that are able to be positioned by elastic means on the impression formed in the edge (7b, 7c) of a control key (7) perpendicularly to the direction in which said key (7) is introduced into the cylinder (3), these pistons (8) being able to take up two positions, namely a position retracted into the cylinder (3) when the key (7) is introduced into the latter and an extended position when the key (7) is withdrawn there from. This system is characterized in that:—the cylinder is made up of a locking block (3) of parallelepipedal shape that is able to be received in a receiving block (5),—it comprises locking means which are activated when the locking block (3) is introduced into the receiving block (5).

The lock according to the invention is meant for locking cabinets, vaults and different machines. The lock has a lock frame, which comprises a bolt. A lock cylinder has been arranged in connection with the lock frame. The lock frame further comprises a power transmission mechanism between the lock cylinder and the bolt. The power transmission mechanism comprises a transmission lever and a latch. The transmission lever additionally comprises a retaining protrusion. The bolt comprises a locking pin and the lock frame additionally comprises a hole for the locking pin. The lock is arranged to allow movement of the lock cylinder and the power transmission mechanism in the direction of the longitudinal axis of the lock cylinder due to an external hit or drilling of the lock cylinder, whereby the movement in the direction of the longitudinal axis moves the retaining protrusion away from the locking pin. Thus, the end of the locking pin moves into the hole in the frame.
