A cable run unit which is constructed from a plurality of tubular elements and can be installed in a curved shape following a polygonal track, onto which cable run tubular elements can be connected on the inlet side and outlet side. The individual tubular elements are constructed from a socket tubular part and an insert tubular part. The insert tubular parts are designed such that they can be inserted into the socket tubular parts with movement play for axial movement and for installation in a curved shape. The socket tubular parts have internal stop collars and the insert tubular parts have outer stop collars to limit the axial movement play. The socket tubular parts have an inner stop collar which is designed as a sealing ring and can be inserted into the socket tubular parts during insertion of the insert tubular parts. The sealing rings rest on the insert tubular parts, such that they produce a seal, in their inserted state. <IMAGE>
