On the cable-laying conduit of rectangular and square cross section, the longitudinal opening for insertion of the cable is disposed in one corner of the conduit cross section. The opening is formed by shortening the two abutting conduit sides. At least three of the four conduit sides have outer fastening strips, extending parallel in the longitudinal direction, for installing the conduit. When the conduit is embodied as a grid structure with longitudinal members and transverse members, two side segments each pointing toward one corner are shortened, inorder to form the longitudinal opening. An embodiment as an extruded profile, for instance of plastic, is also possible. The disposition of the fastening strips or longitudinal members in a spacing pattern is suitable for installation by means of hooked brackets.
