Abstract: The connection device (1) serves for introducing a shielded cable (3) into a housing (2). The connection device (1) comprises a holding element (8) and a core part (7). The core part (7) is electrically conducting and connected with the housing (2). It is equipped at the inner end (13) with a fastening mechanism for the end (18) of the conducting sheath (6) of the cable (3). As holding element (8) can be present connection armourings for corrugated tubing (5), clamping screw connections for cables or other connection devices, In connection with the core part (7) they ensure the secure and simple connection of the shielded cable (3). The conducting sheath (6) of the cable (3) can be part of the cable or be guided loosely about the cable (3).
