The invention relates to a closure for a refueling tank of a motor vehicle. Said closure has a closure cap which can be fixed to a filler neck in a liquid and gas-tight manner. The upper cap part rests against the pipe surface of the filler neck via an annular seating surface equipped with a flat packing. The entry part axially protrudes from the cap part and can be fixed to the filler neck in an axial direction. The aim of the invention is to provide a simple structure, in terms of movement, for reliably achieving an axial connection between the cap part of such a closure and the filler neck. To this end, the entry part is provided with a contacting element which can be reciprocated in relation to an under cut or counter-profile of the filler neck.
