Abstract: The present invention relates to an installation device for cables (6) that are to be laid along walls, with cable holders (5) and a cover (10). The present invention makes provision such that the cover (10) is configured as a cable cover profile strip (1) with a front cover strip (2) and side cover strips (3) that extend from its two side edges (201), which can be wound on to a winding body and then unwound from same in order to be installed; the two side cover strips (3) are connected to the front cover strip (2) through a folding or hinged connection; in the wound-on state (LT), the two side cover strips are folded inward with their unattached side edges (301) facing each other, and extending in the same direction as the front cover strip (2); and in that each of the two side cover strips (3) can be moved into the installation position (MA) by being folded away from the front cover strip (2), transversely to the longitudinal dimension of said front cover strip (2).
