摘要： A resilient clip for retaining a fuel injector housing to a fuel rail cup. The clip includes a pair of opposing sidewalls. Each one of the pair of opposing sidewalls of the clip has a frontal portion and a rear portion. The frontal portion has a pair of inwardly extending shoulders for insertion into a pair of opposing slotted regions into the fuel injector housing. The frontal portion includes a pair of opposing slots formed in the frontal sidewall portions of the clip. The slots of the clip are elevated above the shoulders therein for receiving portions of the lip of the cup. The rear portion has a pair of opposing sidewalls and a backwall. The opposing sidewalls and the backwall of the rear portion of the rear portion form a slot for the clip. The slot is for receiving a tab of the fuel rail cup. When the injector housing, clip, and cup are assembled, the lip of the cup is disposed in the slots of the clip, the shoulders of the clip are disposed in the slotted region of the fuel injector housing, and the tab is disposed within the slot of the clip. Circumferential rotation of the clip about the longitudinal axis of the cup relative to the cup is restrained by engagement of sidewalls of the tab of the cup with the sidewalls of the clip. Circumferential rotation of the clip relative to the injector housing is restrained by engagement of the stops with edges of the shoulders of the clip. Axial motion of the fuel injector housing relative to the cup is restrained by engagement of the shoulders of the clip with the slotted portion of the fuel injector housing and by engagement of the lip of the cup with edges of the slots in the clip.
