A threadless electric connector includes a V-shaped plate spring having wing sections joined together to form a vertex at one end and overlapping arms at opposite ends having openings therein spaced from terminal ends of the arms such that an end portion of one of the arms at least partially blocks the opening in the other arm in an initial condition of the spring. One of the wing sections is attached to a support and electric contact element having a flange lying parallel to the arm of the one wing section and containing an opening. In operation, the wing sections are resiliently movable relatively toward one another for aligning all three openings for the reception of an elongated electric conductor which is clamped in place upon release of the pressure applied.
