The filter housing has a connecting element connectable by a rotary and/or plug-in connection for connecting the filter with a connecting device. The filter housing has a securing ring forming a cup-shaped attachment section with a circumferential free rim. By rotary and/or plug-in movement, the attachment section is attached to an insertion section of the connecting device. The attachment section is provided with a sealing receptacle of a circumferential sealing device. The sealing receptacle is open in radial inward direction and has a radial sealing surface. The attachment section is connected at the free rim with the circumferential wall of the housing pot by crimping. The securing ring provides a first axial stop surface for an annular seal. A stop ring, inserted into the securing ring, provides a second axial stop surface for the annular seal.
