The invention relates to a filter device with a filter element (1) which can be received in a filter housing that consists 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 means of a screw connection (32, 33), and an additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). The invention is characterized in that in order to transmit a torque between threaded elements (33) of the screw connection (32, 33) and of the additional screw connection (41), said threaded elements being rotatable relative to each other, a coupling device (43, 46, 61) is added which allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the screw connection (32, 33) reaches the fixed rotational state. |
