Hook and loop fastener element
The invention relates to a hook and loop fastener element having an electrically non-conductive carrier ( 4 ), preferably made of a plastic material, defining a gripping surface ( 6 ) from which gripping elements ( 8 ) extend that can engage with counter-elements for forming a hook and loop closure, at least one electrical conductor ( 14 ) being present within the gripping surface ( 6 ), characterized in that the carrier is provided in the form of a carrier band defining a longitudinal axis, and that said band is wrapped by the at least one conductor over at least part of the length thereof.
