The invention relates to a filter cartridge (1), especially a suction filter cartridge, which is provided, in the outlet opening (20), with an inward- pointing, peripheral snap-on rim (22) which can be folded from a first lower snap position into a second upper snap position and vice versa. The invention also relates to a seat element (30) for such a filter cartridge, comprising a connecting sleeve (33) which engages with the outlet opening (20) of the filter cartridge (1). Said connecting sleeve (33) comprises at least one actuator which displaces, when the filter cartridge (1) is placed on the rim, the snap-on rim from a first lower snap position to the second upper snap position in which the snap-on rim rests against the connecting sleeve (33) in a sealing and clamping manner.

L'invention concerne une cartouche filtrante (1), en particulier une cartouche filtrante d'aspiration munie, dans l'ouverture de sortie (20), d'un bord périphérique à encliquetage (22) orienté vers l'intérieur, pouvant s'encliqueter d'une première position inférieure dans une seconde position supérieure et vice-versa. L'invention concerne également un élément d'assise (30) pour une telle cartouche filtrante, présentant un manchon de raccordement (33) venant en prise avec l'ouverture de sortie (20) de la cartouche (1). Le manchon de raccordement (33) présente au moins un élément d'actionnement qui, lorsque la cartouche (1) est appliquée sur le bord, déplace ce dernier, d'une première position d'encliquetage inférieure, dans une seconde position d'encliquetage supérieure, dans laquelle ledit bord s'applique de manière étanche et serrée sur ledit manchon de raccordement (33).
