<p>Device (11) for subsequent insertion of cables in ducts (14) provided for this purpose which are already equipped with at least one cable. The device (11) possesses an intermediate element (12) which can be inserted in the duct (14), the element comprising on both sides a longitudinal hollow edge (18, 19) in the form of a bead which serves as a height guide and, on the front face, a rotating wheel (26) serving as a cable guide. To allow easy insertion of the intermediate element (12) even in ducts laid with relatively small curvature radius, the longitudinal edges (18, 19) in the form of beads are provided with a hollow space (21) which is circular in cross-section and with a slot (22) at one point of their periphery and over their entire length.</p> |
