Abstract: The device is a tool for placing a split sheath around elongated items such as bundles of electronic cables. It comprises a guide bush which makes possible the opening of the sheath, a duct for the cables to be sheathed, lateral grooves for guiding the open sheath and is characterized by the presence of a lateral opening which allows the introduction or extraction of cables possibly already fixed at their two extremities during the use of the tool, as well as by the angle which there is between this opening and the duct for the cables in a manner to keep them in position in the tool be their own rigidity. The tool may have a handle for manipulation and for setting the tool in relative motion along the cables to be sheathed. The invention is also directed at the method for using the tool.

Abstract: A method of applying a knotted lacing cord or yarn to an elongated bundle of electrical wires comprises the steps of forming a set of loosely knotted adjacent loops of larger diameter than the bundle from a continuous length of a lacing cord, passing the plurality of loops over a free end of the bundle, securing the first loop at an adjacent said free end by knotting or otherwise clamping it thereto followed by pulling on the free opposite end of the lacing cord to progressively tighten successive loops about the bundle, at spaced intervals along the length of the latter.
