A tank closure for a fill opening of a fuel tank has a closing device extending axially through the fill opening of the fuel tank. The closing device includes a grip for actuating the closing device. The closing device also includes a first clamping member and a second clamping member movable axially toward one another. The first clamping member has a first clamping surface and the second clamping member has a second clamping surface. The first and second clamping surfaces face one another and define therebetween an annular chamber. The first and second clamping surfaces are positioned at an angle .alpha. to one another. The closing device also includes a radially elastically expandable sealing ring positioned in the annular chamber.
