Abstract

A closing device for a vacuum user system or vacuum toilet system of an aircraft that makes it possible to quickly open and close a pipe connection piece in a vacuum user system or in a vacuum toilet system of an aircraft. The closing device comprises a cover; a closing element that can be inserted into the pipe connection piece and is connected to the cover by a spacer and is designed such that it substantially fully covers a cross section of the pipe connection piece; a sealing bellows located between the cover and the closing element and that at least partly encloses the spacer, wherein the sealing bellows comprises a sealing face; and an element that is movable in relation to the cover, which element is movable from a first position to a second position, wherein the movable element engages the sealing bellows such that the sealing face of the sealing bellows in the second position has a greater extension in a plane across the spacer than it does in the first position.
