The retainer clip is attached securely to the socket nose end of an injector by a plurality of evenly spaced apart claw elements extending laterally from one side of a planar annular central disk section of the clip at the periphery thereof. An equal plurality of retention spring fingers extending laterally from the other side of the disk periphery are provided to givingly enter a fuel port aperture in a fuel rail injector socket. The claw elements and retention spring fingers have spring sections disposed in the plane of the disk. Additionally, the spring fingers have second spring sections extending laterally from the the first spring sections. Preferably, the claw elements are located at diametrically opposed peripheral positions from those of the spring fingers.
