摘要

The invention relates to a tubular fabrication 10 of plastic material. There are electrically conductive areas 11 on the inner surface of the tubular fabrication 10 and there are electrically conductive areas 12 on the outer surface of the tubular fabrication 10. The electrically conductive areas 11, 12 have been brought into electrical contact by means of an overlap of the inner surface and the outer surface of the tubular fabrication 10. <IMAGE>
