Abstract

La présente invention a pour objet un système de sécurité pour serrures de sûreté à cylindre. Ce système comprend un cabochon tournant 5 monté, libre en rotation, autour du cylindre 2 par l'intermédiaire d'un manchon autolubrifiant 12 ou analogue, et qui tourillonne, retenu longitudinalement par sa collerette annulaire 10, dans l'orifice 4 de présentation de ce cylindre 2 à l'intérieur de la porte 3. Il trouve une application intéressante chaque fois que l'on désire protéger le cylindre 2 des tentatives de détérioration à la clé à griffes ou à la chignole.
