<p>A draw wire, particularly for inserting electrical wires in conduits, of the type constituted by an elongated body (11) made of plastics whose flexibility allows it to be inserted in conduits with bends while maintaining an extended configuration. The draw wire has a transverse sectional profile which has at least one portion of its cross-section which is substantially flat and is extended longitudinally with a guiding surface (11a, 11b, 11c, 11d) for its winding/unwinding, at least one longitudinally extended grip surface (12a, 12b, 12c, 12d) being formed parallel to the at least one guiding surface (11a, 11b, 11c, 11d) and being provided with protrusions arranged in an orderly arrangement and designed to engage corresponding pushing and pulling means for the movement of the draw wire (10).</p> |
