Abstract

L'invention porte sur un agencement de serrure, qui comprend un boîtier de serrure (10, 110) recevant un pêne (11, 111) qui peut être déplacé de façon linéaire dans une première direction entre une position de verrouillage étendue et une position de libération ; et une plaque de montage (12, 112) qui est fixée au boîtier de serrure. La configuration de serrure comprend au moins un élément de blocage (17, 108) comportant une cavité de réception de pêne (18, 109). La plaque de montage comprend une première partie (13, 113) qui est fixée au boîtier de serrure et une deuxième partie (14) qui est conçue pour être fixée à une porte (3), à un cadre, ou analogue. La première partie est fixée à la deuxième partie, et est mobile par rapport à la deuxième partie et à l'élément de blocage dans une direction qui est non parallèle à la première direction. Le pêne comprend une partie de base (21, 121) et au moins une partie de crochet (22, 122), qui fait saillie à partir de la partie de base dans une direction qui est non parallèle à la première direction et qui est agencée de façon à venir en prise avec un bord de la cavité de réception de pêne lorsque la première partie de la plaque de montage est déplacée par rapport à la deuxième partie pour empêcher le déplacement du pêne vers la position de libération.
