The invention: relates to plug-in device that unj solvable with? the supply line are connected, and an elastic Have insulating material body *

In the case of plug-in devices of the type mentioned, the contact parts are often embedded directly in elastic insulating material bodies without the use of support members. Metal molds in which the shaping takes place under the influence of pressure and heat «: during extrusion. With insulating material, tensions arise, which primarily stress the conductor and the connection points between the conductor and the contact part

SHEET NUMBER. 2. TO LETTER FROM

The technical parts described are replaced by the present Invention Avoided For this purpose, the line wire connected to the contact part is preferably inserted laterally Loop shape applied to the contact part and by an overdrawn, elastically acting fastening means, in iorm one Insulating hose or a cupon ring lightly pressed on. This ensures that the strain relief remains fully effective without an impermissible and uncontrollable Displacement of the vein loops during the "wrapping with the Insulating material takes place.

Another advantage of the inventive arrangement is given in device sockets, coupling sockets and the like. Here effected the insulating hose pushed over the contact sleeve and preferably reaching to the end face of the socket, that neither laterally through the longitudinal slot nor from the front insulating material can penetrate into the contact sleeve. This is particularly important when contact sleeves with rectangular Cross-section "are used because the subsequent removal of the penetrated insulating material with considerable Effort is involved. With regard to a uniformly designed insulating body, it is advisable that the insulating fabric made of the same elastic material as the Isolate off body "consists. -..- .. ■.
