A filter device includes a pot-shaped filter housing ( 1 ) that defines a longitudinal axis along which a filter element ( 13 ) can be inserted into and removed form the filter housing ( 1 ). A retaining device detachably retains the filter element ( 13 ) in the filter housing ( 1 ) and has first and second retaining elements on the inner side of the filter housing ( 1 ) and on the filter element ( 13 ) and interacting with one another. At least one set of the retaining elements has a shape coaxial to the longitudinal axis of the filter housing ( 1 ) and forms at least a part of a thread. When the filter element ( 13 ) is rotated about its longitudinal axis, it is locked in a form-fit.
