Abstract
A device for sealing the gap between the opening of a tank and a filler pipe passing movably through the opening. It includes a coupling tube which can be placed in the gap and which can be sealed against the opening at one end and against the filler pipe at the other by radially inflatable gaskets. The inwardly facing second gasket is disposed at a distance above the opening and the first gasket, and the coupling tube has at least one secondary opening in the area between the first gasket and the second which serves for the connection of a vacuum line or a pressure line.
