A cable-routing device, the members of which have central joint bodies for articulation to one another, which comprise a joint head and a joint socket. The joint head has an axial region in which the cross-section thereof has a peripheral geometry with at least two corner points and lateral lines which connect the latter to one another, the lateral lines which meet at a corner point forming an internal angle of less than 180°, and the joint socket has a receiving region which geometrically corresponds to the axial region of the joint head and into which the joint head can lock.
