The proposed turning device of a duct for laying cables and wires contains sections with swing joints that are designed for turning the duct. Each section has U-shaped cross-section and is closed by a shaped cover. The side walls of the sections are joined by coupling plates. On one side, the coupling plate is shaped as a semicircle and contains a central hole, which is designed for the bolted joint of the plate with the section wall, and holes for fastening parts, which are designed for fixing the specified angle position of the section. On the other side, the coupling plate is shaped as a rectangle and contains oval holes, designed for coupling the plate with the wall of the adjacent section. The edges of the side walls of the sections are bond with a defined round radius, according to a specified profile, for a possibility to be fixed to the section cover.
