Zusammenfassung:	The invention concerns a filling fitting for a fuel tank of a motor vehicle having an automatic tank closure. The filling fitting includes a carrier with an inlet opening and a closure cover, which closes the inlet opening with a sealing element. An upper side of the closure cover has a closure component, which, in a closed position of the closure cover, penetrates the inlet opening. Above the carrier is a circumferential section placed directly or indirectly on a supporting closure ring. The section extends inward to coact with closure elements on the closure component in the manner of a screw drive. To prevent permeation, in a force transmission path between the sealing element of the closure cover and the carrier, at least one axial, effective spring element is inserted.
