A retaining clip for retaining a threaded screw on a wall of an outlet box has a pair of legs extending generally parallel from a bite portion and which are received in slots in the wall extending across an elongated screw receiving passage. Each leg has an opening having a diameter substantially equal to the major diameter of the thread and each opening has a projection having an inner arcuate edge having a radius of about one-half the minor or root diameter. At least one of the openings has its center axially offset from the axis of the passage so that a line through the two centers is inclined with respect to the axis of the passage.
