Abstract: An electrical terminal assembly for releasably connecting a branch lead to a through lead without disturbing the continuity of the through lead has an insulating housing in two, snap-engaging parts fitted on opposite sides of the through lead. The body part holds a metal terminal member made from a flat blank and formed at one end as a socket of a flat blade plug and socket connector. A flat blade connector on the branch lead can be inserted in the socket through an aperture in the body part. The other end of the terminal member is bent into tubular shape leaving a gap between its edges. An aligned slot is formed in the opposite wall. The edges of the gap and slot pierce the insulation of the conductor and make contact with its core when the two body parts are interengaged about the conductor.
