jaw members extending longitudinally inward from its lateral edge (41a) and each plate-portion being interconnected so that the jaw members cooperate to form one common jaw for simultaneously receiving the blade, each pair of jaw members defining a longitudinally extending and laterally narrowing slot (46) which includes an opening (46a) on the lateral edge (41a) and an inward narrowed portion (46b, ) the opening (46a) being sized to receive the blade and the narrowed portion (46b) being sized to form a constriction for holding the blade. ### Claim 12 (depends on 11) An electrical contact as required by claim 11 wherein each of the plate-portions (40a, 40b) are substantially parallel to one another. ### Claim 13 An electrical connection, comprising: a pair of housings (10, 20)
