The fastening device includes an annular guide eyelet having an end face, a half-shell-shaped fixed clamping jaw which is integrally molded on the end face, and a loose clamping jaw configured to be clamped to the fixed clamping jaw. In an assembled state, the half-shell-shaped fixed clamping jaw and the loose clamping jaw are configured to clamp the metallic protective tube. The fastening device further includes at least one of the half-shell-shaped fixed clamping jaw and the loose clamping jaw comprising a receptacle-forming clamping jaw having an inner surface that forms a receptacle configured to receive the earthing contact.

Abstract: An electrical plug-in connection has a plug part with contact pins and a socket part with socket contacts. Coding elements interact in accordance with the lock/key principle in order for the two parts to be fixed in place in a pre-defined relative plug-in position. One or more protrusions, and apertures complementing the protrusions, are provided on the plug or socket parts. On being connected, one protrusion each is incorporated in an aperture, engaging behind the periphery of the associated aperture in the process. The aperture has two adjacent accommodating chambers. A plug-in accommodating-chamber periphery that is directed away from the plug-in direction, is at such a low level that the associated protrusion slides over it in the plug-in direction, and an arresting accommodating-chamber periphery is at such a high level to effectively prevent sliding of the protrusion over the arresting accommodating-chamber periphery.

Abstract: An electrical contact-making system includes a flat ribbon cable with a sheath which has a planar top sheath face, a core plane containing electrical cores and a bottom sheath face with constricted portions which are parallel to the cores and are each disposed between two of the cores. A tapping collar makes electrical contact with the cores. A peripheral sealing strip encloses a rectangular contact-making region and is disposed on a bottom face of the top part of the tapping collar facing the top sheath face of the flat ribbon cable.
