Abstract

A filter device has a filter housing of connected housing parts with an inlet for unfiltered fluid and an outlet for filtered fluid. A filter element arranged in the filter housing separates the inlet seal-tightly from the outlet. A releasable anchoring device connects the housing parts. The anchoring device has a rotary insert having a guide and anchoring section and an interacting receptacle with an insertion/removal section. The rotary insert of the first housing part is arranged in the receptacle of the second housing part. The guide and anchoring section has a first rotary state in which it is positively guided for gliding in the insertion/removal section to guide the housing parts when being connected or separated. In a second rotary state the guiding and anchoring section is secured in an anchoring section of the receptacle for securing the housing parts. The insertion/removal section passes into the anchoring section.
