Abstract
A filter device has a filter element (1) received in a filter housing of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by one screw connection (32, 33). An additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). To transmit a torque between threaded elements (33) of the one screw connection (32, 33) and of the additional screw connection (41), the threaded elements are rotatable relative to each other. A coupling device (43, 46, 61) is added that allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the one screw connection (32, 33) reaches the fixed rotational state.
