Abstract

A filter device for fluids with a fluid inlet (14) and a fluid outlet (24). A filter element (9) is enclosed by an end cap (21) on its lower end facing a bottom part (5) of the filter housing (1). The end cap has a passage (29) forming a fluid connection to the filter element inner filter cavity (17) and can be fixed to an element retainer (23) of the filter housing (1). The element retainer (23) includes a retaining piece (35) open towards the filter element (9) with a fluid channel (37) leading to a housing connection (24). The end cap (21) has a connecting piece (27) in the retaining piece (35). The retaining piece (35) forms an opening (43) connected to the fluid channel (37) leading to the element retainer (23). A sealing (45, 47) seals the opening from the open end of the retaining piece.
