Zero insertion force connector clip assembly for connecting conductors on a flexible film to conductors on a circuit board comprises a stamped and formed metallic clip and a lifting tool mounted on the clip. The clip has cantilever springs extending from one of its side edges towards the surface of the circuit board. The springs are arcuately formed to define bearing portions which bear against the circuit board conductors and each spring has a portion extending from the bearing portion towards the clip bar. Each spring also has a tool engageable section which extends substantially parallel to the clip bar. The lifting tool comprises a platelike member mounted against the clip bar having edge portions disposed between the end portions of the spring and the clip bar. The springs can be raised from the surface of the circuit board by manipulating the tool as a lever to raise the bearing portions of the springs so that a cable can be inserted beneath the bearing portions.
