The inner surfaces of the bushings (2) for the contact elements (3) in strip bodies (1) are coated over at least a part of their length with contact grease (4) so that, as a consequence of the increased surface tension, soldering flux is prevented from penetrating into the contact region (5) of the contact elements (3). The invention is mainly used in the case of male connector strips of multi-pole plug connectors. <IMAGE>
