Abstract (en)
[origin: FR2682147A1] A cylinder lock having a prismatic end-fitting (3d) for the nesting of a key (1) includes a socket (2) for retaining the key when the lock is not in a closed position. The socket (2) is secured by holding fingers (2a) to the cylinder (3) and is immobilised in terms of rotation by immobilisation fingers (2b) engaged in a groove of the rose. The socket (2) includes a folded-down collar (2d) having two notches (2c) for the passage of two studs (1c) of the key (1). After the key (1) has been put in place, with the lock closed, a rotation of the key (1) brings the studs (1c) behind the collar (2d), preventing any withdrawal of the key (1). <IMAGE>
