The invention concerns a hose-like blank (10) of a plastic material. On the inner face of the hose-like blank (10), there are electrically conductive areas (11), and on the outer face of the hose-like blank (10), there are electrically conductive areas (12). The electrically conductive areas (11, 12) have been brought into electrical contact by means of overlapping of the inner face and the outer face of the hose-like blank (10).
