The line connection (10) connects a first line (14.1) via an intermediate line (12.1) with a second line (16.1) and, functionally parallel therewith, a first branch line (14.2) via an additional intermediate line (12.2) with a second branch line (16.2). The line connection (10) itself comprises two coaxial cylinders (20, 22), which are rotatable in relation to each other, and a planet wheel (24) disposed in the space between the cylinder (20, 22), as well as the intermediate line (12.1) and the additional intermediate line (12.2). Connections (18.1, 18.2) of the first line (14.1) and the first branch line (14.2) to the intermediate line (12.1) and the additional intermediate line (12.2) are disposed on one of the cylinders (20 or 22), and on the other of the cylinders (22 or 20) the connections (19.1, 19.2) of the intermediate line (12.1) and the additional intermediate line (12.2) to the second line (16.1) or the second branch line (16.2). In a zero position all connections (18.1, 18.2, 19.1, 19.2), the intermediate line (12.1) and the additional intermediate line (12.2) as well as the planet wheel (24) are arranged mirror-inverted in relation to a plane of symmetry (S), which is defined by the axes (M) of the cylinder (20, 22) and the axis (N) of the planet wheel (24), wherein the intermediate line (12.1) and the additional intermediate line (12.2), starting at the connections on one cylinder, each encircle one half of the planet wheel in a complementary manner and are then continued to the connections on the other cylinder. With a suitable design, a relative rotation out of the zero position by at least 360.degree. is possible in each direction of rotation.
