<p>Strip has a core (2) made of a flexible deformable material and a casing (3) made of a flexible conductive textile fabric. The cross section of the core corresponds to a low isosceles triangle. A section of the casing forms an even bearing surface (4) on which adhesive strips (7a,7b) are attached. The casing forms two-ply plates (6a,6b) within the range of slot sided edge of the bearing surface.</p>
