A filter device has a support part (39, 43) receiving a filter part (1), a sealing device (17) acting between the support part (39, 43) and the filter part (1), and a securing device (53, 57, 61) releasably connecting the support part (43) to the filter part (1). The securing device has a circumferential collar part (53) that, under the action of an energy store (61), exerts a force on the sealing device (17). That force seals the support part (39, 43) and the filter part (1) in a fluid-tight manner with respect to one another. The support part (39, 43) has, on its end region oriented toward the securing device (53, 57, 61), another circumferential collar part (39). The collar part (53) of the securing device (53, 57, 61) is guided concentrically within the collar part (39) of the support part (39, 43) provided with a sealing system (41, 72).
