A housing for a circuit breaker is molded with a recess and projection, for receiving a connector clip having contact blades joined by a bight. The bight has a fixed length with a first projection toward, and a longer second projection away from, the blades. The second projection is connectable to an electrical circuit. The inner surfaces of the blades are engageable with a bus bar. A clamping holder for the clip comprises an integral sheet metal member, and includes a mounting plate having a hole for retaining the clip at the bight. A flat spring means is coupled at one end by a substantially perpendicular bend to the plate and has an opposite end formed as two flat springs separated by a slot that terminates before the bend to stiffen the plate. Torque arms, coupled at one end to the flat springs at an acute angle therewith, at their other ends have opposing portions engaging the outer surfaces of the blades. Engagement of the bus bar with the inner surfaces of the blades transmits motion to the arms. This motion places the flat springs in torsion, producing a contact connecting force between the blades and the bus bar to supplement a primary force exerted by the blades. The holder is externally shaped to engage the housing recess and projection for stably mounting the clip within the housing.
