ABSTRACT:
The invention relates to a cylindrical filter element, which has a longitudinal slot in order to be able to expand the filter element elastically for the purpose of fitting in a circumferential groove. To prevent any fluid from being able to pass unfiltered through the longitudinal slot, the invention proposes to configure end faces, which delimit the longitudinal slot, such that they run in the secant direction or in the peripheral direction. This has the advantage that the end faces overlap and therefore the longitudinal slot is closed when the filter element is installed.
