Abstract
A filter (18) is fastened by means of a releasable detent connection (20) in a fastening housing part (14). One detent component (32) is connected to the filter element (18) and one detent component (36) is connected to the fastening housing part (14). At least one detent means (32) of one of the detent components engages in a bayonet-like manner in a cut-out (38) in the other detent component (36). One switching component (60) of a switching device (58) is connected to the filter element (18) and one switching component (62) is connected to the fastening housing part (14). One of the switching components (60) includes at least one switching lug (76) extending radially to a rotational/plug-in axis (30) of the filter (10), and one of the switching components (62) includes a switching slot (78) for guiding the switching lug (76). The switching slot (78) guides the switching lug (76) and thereby effects a rotational movement of the filter element (18) relative to the fastening housing part (14 to move the detent means (32) out of an insertion/withdrawal region (46) into a closing region (40) of the cut-out (38), or out of a retaining region (42) into the insertion/withdrawal region (4…
