Abstract: A device for laying and suspending cables (38), in particular low-voltage, medium-voltage and signal cables, is fitted in a man-sized duct or tunnel with brackets (10) secured in spaced relationship on the inner periphery of the duct or tunnel or on diagonal braces. These brackets are used for supporting cables (38) drawn in guide tubes (32).The brackets (10) projecting into the duct or tunnel are made tubular and have at least one flat outer surface (42, 44) extending over the entire length. The brackets are equipped with a locking device (22) at the free end (20).A guide connection (24) of at least one tube saddle (26) having a hard-plastic cable guide tube (32) which runs approximately at right angles to the longitudinal axis (A) of the guide connection (24) and of the bracket (10) and has a low coefficient of friction is arranged on each bracket (10).
