A fuel injector retention arrangement for connecting a fuel injector with a fuel rail comprises a fuel injector receiving cup having a fuel rail end in connection with a fuel rail and a fuel injector insertion end into which a fuel injector is insertable and connecting pins, the connecting pins being insertable into the receiving cup in such a manner, that a longitudinal axis of the connecting pins is situated in a first plane, which is oriented perpendicularly to a longitudinal axis of the receiving cup. The connecting pins are arranged in apertures of the receiving cup. A longitudinal axis of the apertures and the longitudinal axis of the connecting pins are aligned with each other. The apertures have an insertion end into which the connecting pins are insertable and a shoulder forming an axial stop for the connecting pins at a second end of the apertures. The apertures have a service opening which is arranged between the shoulder of the apertures and an outside surface of the receiving cup. The service openings are defined by a first side surface radially extending away from the second end of the first aperture and the longitudinal axis of the apertures, a second side surface extending along the longitudinal axis of the first aperture and away from the first aperture, and a third side surface and a fourth side surface. The first side surface and second side surface extend between the third side surface and fourth side surface.
