A movable coupling for a pipeline, which can be applied in aviation and aerospace. The coupling includes a dip pipe, a counter piece and a displaceable component. The counter piece has a passage, into which the dip pipe is inserted. The counter piece has a holder extending from the passage. The component includes a clearance that the dip pipe extends through. A portion of the displaceable component is received in the holder so the displaceable component can be displaced relative to the counter piece in a direction not parallel to the longitudinal axis of the dip pipe. When the dip pipe moves relative to the counter piece, the displaceable component is tight against the dip pipe and also against the counter piece. A tank arrangement includes a tank with a pipeline connected to the tank and including a movable coupling.

1. An aircraft or spacecraft comprising a tank arrangement, the tank arrangement comprising: a tank;a pipeline connected to the tank; anda movable coupling for the pipeline, the movable coupling comprising a dip pipe; a counter piece comprising a passage, into which the dip pipe is inserted, and a holder configured to extend from the passage; and a displaceable component comprising a clearance, through which the dip pipe is configured to extend;wherein a portion of the displaceable component is received in the holder in such a way that the displaceable component is displaceable relative to the counter piece in a direction which is not parallel to the longitudinal axis of the dip pipe;wherein, when the dip pipe moves relative to the counter piece, the displaceable component is tight against the dip pipe in a first sealing region and also against the counter piece in a second sealing region; andwherein the movable coupling is configured to couple the pipeline to a connection which is movable relative to the tank for a fluid-bearing connection of the tank to the connection. 2. The aircraft or spacecraft according to claim 1, wherein the first sealing region is arranged in a region of a surface of the clearance which faces the dip pipe. 3. The aircraft or spacecraft according to claim 1, wherein the displaceable component, as viewed in a cross-section in the plane in which the longitudinal axis of the dip pipe is positioned, is formed with a rounding in the first sealing region. 4. The aircraft or spacecraft according to claim 1, wherein the displaceable component is formed in two or more parts with a base body and a resilient sealing element which is tight against the base body and, in the first sealing region, against the dip pipe. 5. The aircraft or spacecraft according to claim 4, wherein the base body is provided with a groove in the first sealing region and wherein the sealing element is in the form of a sealing ring, which is laid in the groove. 6. The aircraft or spacecraft according to claim 5, wherein the sealing element is in the form of an 0-ring which is laid in the groove. 7. The aircraft or spacecraft according to claim 1, wherein the holder comprises mutually opposing walls which are not parallel to the longitudinal axis of the dip pipe and between which the displaceable component is displaceably guided, the second sealing region being arranged in the region of at least one of the walls. 8. The aircraft or spacecraft according to claim 7, wherein one of the walls is provided with a groove in which a sealing ring, is provided in such a way that the displaceable component is tight in the second sealing region. 9. The aircraft or spacecraft according to claim 8, wherein the sealing ring provided in the groove is an O-ring. 10. The aircraft or spacecraft according to claim 1, wherein the holder is in the form of a shaft which completely encloses the dip pipe in a circumferential direction of the dip pipe and which extends outwards from the passage. 11. The aircraft or spacecraft according to claim 1, wherein an external cross-section of the dip pipe and an internal cross-section of the clearance of the displaceable component are each substantially circular in form. 12. The aircraft or spacecraft according to claim 1, wherein the tank is a waste water tank. 13. The aircraft or spacecraft according to claim 1, wherein the displaceable component, as viewed in a cross-section in the plane in which the longitudinal axis of the dip pipe is positioned, tapers towards the first sealing region. 14. The aircraft or spacecraft according to claim 1, wherein the displaceable component, as viewed in a cross-section in the plane in which the longitudinal axis of the dip pipe is positioned, is formed with a rounding in the first sealing region, and wherein the displaceable component, as viewed in a cross-section in this plane, tapers towards the first sealing region. 15. The aircraft or spacecraft according to claim 1, wherein the aircraft or spacecraft is an airplane.
