An electrical plug-and-socket connector for conductive foils is designed so that it continues to operate reliably long-term under rough operating conditions. For this purpose, the plug-and-socket connector has a plug that can be assembled from a top part and a bottom part with the conductive foil glued into the plug and therefore sealed between these parts when the top part and the bottom part are joined. Furthermore, a sealing element is mounted peripherally on the plug, which is in close elastic contact with a peripheral sealing surface of the socket when the plug is inserted in a socket, and seals the joint between plug and socket. The electrical plug-and-socket connector for conductive foils is intended particularly for use in automobiles.
