Also another well-known one
Patent specification 561 078) is diarch EiBSötaen in a clamping device after the stripped end of the cable has been tied to && n lead wires.

the
Is is / Atii * handover of the invention to provide a Kabelendhtxlse the aforementioned G-attimg to scnaffen which ensures with absolute safety against electric shocks a fixed and kink-free mounting of the cable end in the Elem & vorrichttang * without a complicated machining or Torbereitung the cable EAAE & B Iuz ¹ W * of the sleeve is required before use *

Solution of this object, the invention provides that the Höhrstück * is widened at its base a flange mi "which is enclosed in an insulating ring, the klesmend up in a on the end portion of the cable insulation. Slidable insulating sleeve with a cylindrical bore forfeetat. In the design according to the invention, the metallic tube provided for receiving the wire end is followed by an insulating sleeve which, due to its cylindrical inner bore, rests firmly on the insulation of the cable, so that the conductor wires themselves are separated from the cable Task of a holder of the cable in the Kleamvorrichtung is largely freed. @ leiohwöhl the Kabelendhüläe according to the invention can not only be produced economically in mass production, but it can also be used without the use of a tool

Its "special" form of execution provides that the ianeix zyXindrisöhe sleeve is twisted around with »longitudinally extending ribs» Zw & t are longitudinally extending ribs in electrical plugs at sioh known (USil-Patentsöhrift 3 204 215); In the "known arrangement", however, the cable insulation is always on the resiliently yielding ribs on the opposite side, especially before the cable insulation is held by the cylindrical inner sleeve of the sleeve, particularly before the end sleeve according to the invention the longitudinal ribs serve as a sütisätzliehen connection and holder of the cable end sleeve on the line insulation *

This means that the opening of the joint ends is pushed on "favors" that the Hippen © a lead-in end of the bore spits jsulaiafen -und sichaam. fiohrstUok Mn conical after expand inside

Preferably, the outside Hing has a henkelfSriaigen approach for attaching Xeltunge markings on _r which can be readily provided in one operation with the production of the binges "
