Abstract: The invention relates to an apparatus providing a means for the connection of filamentary or stranded wire electrical conductors to contact members such as cut-clamp elements extending from a printed circuit board, which apparatus accommodates a conductor transversely to its normal running direction in a detent slot open on one side, and in which the contact members are arranged on a base plate; a cover plate connectable with the base plate is provided in order to press a portion of a conductor line running between the base plate and cover plate into a detent slot and to maintain it in the pressed-in state between the base and cover plates.
