An apparatus (11) is described for the subsequent insertion of cables into ducts (14) provided for this purpose and already equipped with at least one cable. The apparatus (11) has an intermediate bottom (12) which is insertable into the duct (14) and is provided on both sides with a hollow bead-like longitudinal rim (18, 19), as a height guide, and on the front with a rotatable roller (26), as a cable guide.To enable simple insertion of the intermediate bottom (12) even in cable ducts (14) laid with relatively short radii of curvature, using an apparatus (11) of this kind, the bead-like longitudinal rims (18, 19) are provided with a hollow space (12) of circular cross section and with a slit (22) at one point on their circumference and extending over their entire length.
