Abstract
A filter assembly (10) including a housing (11) which is used to receive a filter medium and is closed by a lid or cover (14) in a sealed manner. The cover (14) is fixed by fixing elements (15) to an axial end face of the housing (11), and a seal is arranged between the cover (14) and the housing (11). Fixing contours (24) are provided on the outer peripheral surfaces of the housing (11) on the front side of the assembly. The fixing element (15) is arranged on the outer front side of the cover (14) so as to be pivotable such that the fixing element (15) can be displaced essentially parallel to the front side of the cover (14). When positioned parallel to the front side of the cover, the fixing element (15) creates a positively locking connection between the cover (14) and the housing (11), and when in the opened and pivoted state, the fixing element (15) forms a grip or handle for handling the cover (14).
