A multifunctional comb includes an upper half-comb provided to be mounted on a support and a lower half-comb provided to be mounted on the support through the upper half-comb and a screw system. The half-combs have arches facing each other to grip the piping. In addition, each of the half-combs has at least two half-bores located in front of each other to form bores of the comb, as well as inter-arches connecting faces. The half-bores, the arches and the connecting faces are continuously covered by an electrically conductive coating in order to ensure the plating function. Moreover, the half-bores, the upper half-comb and the bottom half-comb include structure coupled to the half-combs that can be secured to the support respectively in a temporary and permanent way.
