A multi-pole electric plug connector including a metallic housing. To ensure protective grounding of the housing, a bracket-shaped electrically conducting connector, which is resilient in the axial direction and laterally extends around a contact holder in the housing, and which is axially elastically pushed down by the housing so that contact is made with the housing, and through which a grounding contact extends so as to connect the housing to the grounding contact in an electrically conducting manner.
