Abstract
A gaseous fluid filter has a filter element insertable into the filter housing through a service opening. A clamping wedge is insertable in a joining direction for clamping the filter element in clamping direction against the filter housing. The filter element rests against the filter housing with a seal surface facing away from the clamping wedge. The clamping wedge has a housing wedge side facing a housing stop and a filter element wedge side facing a filter element stop. These wedge sides each have first and second bearing surfaces separated by a step. The joining direction extends in or parallel to a contact plane between housing wedge side and housing stop. The first and/or second bearing surface of the filter element wedge side is positioned at a wedge base angle of 1° to 20° to the joining direction. The steps of the wedge sides are offset in joining direction.
