A filter closure system has a connecting head with a connecting web and further has a connecting end at an end face of a filter housing. The connecting head and the connecting end are matched to one another. The connecting end is pushed onto the connecting head in a mounting direction into a mounted state on the connecting head so as provide a seal-tight connection in the mounted state. The connecting end and the connecting web that extends in the mounting direction are provided with a micro toothing. When pushing the connecting end onto the connecting head in the mounting direction, the micro toothing connects by positive locking action the connecting end and connecting head with one another. The engagement of the micro toothing between connecting end and connecting head is realized along a flank of connecting web and connecting end which flank extends in the mounting direction.
