Fluid injection assembly

A combustion engine for a vehicle, the combustion engine comprising:

• a fuel rail;
• and
• a fuel injector assembly comprising:
• a fuel injector, and
• a coupling device for hydraulically and mechanically coupling the fuel injector to the fuel rail,
• wherein the fuel injector has a central longitudinal axis and the coupling device comprises:
• a fuel injector cup,
• a plate element,
• one or more screws, and
• a wing clip,
• wherein the fuel injector cup is configured to be hydraulically coupled to the fuel rail and configured to receive a fuel inlet portion of the fuel injector,
• wherein the plate element comprises a central opening through which the fuel injector extends and at least one through-hole for fixedly coupling the fuel injector cup with the plate element by the screw or screws respectively, such that the fuel injector cup, the plate element, and the screw(s) are positionally fixed with respect to each other, and
• wherein the wing clip is arranged at least partly around the fuel injector and extends outward in a radial direction such that the one or more screws bear on a surface of the wing clip without passing therethrough said surface and thereby block a movement of the fuel injector relative to the plate element in a first direction along the central longitudinal axis by a mechanical interaction with the wing clip but do not screw into the wing clip and thereby allow a movement of the fuel injector in a second direction opposed to the first direction along the central longitudinal axis.
