What we claim as new and desire to secure by Letters Patent of the United States is:

1. An electric fixture (or use with a cable having spaced longitudinal conductors comprising a' base having an opening in one side thereof, contacts carried by said base, means for securing said contacts to the base including drive pins having pointed ends, a plate pivoted to the base and movable away from the base to permit insertion of the cable in the base, means for clamping the plate to the base whereby said cable is clamped between the plate and said contact pins with said pointed ends engaging the conductors of said base for closing said opening.

2. An electric fixture for use with a cable having a pair of longitudinal insulated conductors arranged side by side, comprising a base having an opening in one side thereof, connector means carried by said base within said opening, means for securing said connector means to the base including pins having pointed ends, a securing plate pivotally mounted on said base and being movable away from the base to permit insertion of the cable in said opening, means clamping the plate to the base within said opening whereby the cable is clamped between the plate and the pins with said pointed ends piercing the insulation of the cable and engaging the conductors to connect them electrically to said connector means, a back plate pivotally mounted on said base for closing said opening, and means securing the back ,plate to said base.
