The invention relates to a plug comprising a plurality of contact elements located in a plug housing and strain relief elements (200, 200′) arranged on the housing (110, 310), wherein both contact elements and strain relief elements can be fixed to a printed circuit board (10) using SMT technology. The invention is characterized in that the strain relief elements (200, 200′) are sheet metal elements that can be fixed to parts of the plug housing and are bent essentially at a right angle on the side facing the printed circuit board (10), thereby forming a bearing surface (220, 220′) for SMT attach.
