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 connection 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-on rim from a first lower snap position to the second upper snap positioning which the snap-on rim rests against the connecting sleeve (33) in a sealing and clamping manner.
