Abstract: The invention relates to a multipart pipe joint (10) having a centre piece (16) on which joint parts (18, 20) are received which are pivotable relative thereto and which are rotationally fixed to the centre piece (16) at articulation points (22, 24). The articulation points (22, 24) of the joint parts (18, 20) on the centre piece (16) also represent articulation points (22, 24) for transmission elements (42) which extend axially along an inner wall (34) of the centre piece (16). The articulation points (22, 24) forming articulation axes are arranged in an axial offset (25) to each other. Furthermore, the invention relates to the use of the multipart pipe joint (10) in an aircraft.

Abstract: The invention relates to a pipe connection (10, 52, 66) with a first pipe part (12) and a second pipe part (14), with at least one multi-part sealing ring (24; 44, 46) or at least one single-part sealing ring (68) which is surrounded by a clamping device (16). The pipe parts (12, 14) each comprise a first obliquely or vertically extending end face (20, 72) or a second obliquely or vertically extending end face (22, 74). These are overlapped by a clamping device (16). This applies an outwardly acting radial force (34) to the at least one single-part sealing ring (68) or the at least one multi-part sealing ring (24; 44, 46). These are secured in their respective sealing position by means of an enclosing geometric triangle, by means of an enclosing geometric non-rectangular quadrilateral (104) or by means of an enclosing geometric rectangular quadrilateral (106).
