<p>The invention relates to fuel injector assembly (60) with a fuel injector (20) and a coupling device for hydraulically and mechanically coupling a fuel injector (20) to a fuel rail (14) of a combustion engine (22). The fuel injector (20) has a central longitudinal axis (L). The coupling device (50) comprises a fuel injector cup (30) being designed to be hydraulically coupled to the fuel rail (14) and to engage a fuel inlet portion (24) of the fuel injector (20), a plate element (38) being fixedly coupled to the fuel injector cup (30) and comprising a groove (27), and a snap ring (42). The snap ring (42) is arranged in the groove (27) and is designed to fixedly couple the plate element (38) to the fuel injector (20) to retain the fuel injector (20) in the fuel injector cup (30) in direction of the central longitudinal axis (L) and to prevent a movement of the fuel injector (20) relative to the plate element (38) in a first direction (Dl) of the central longitudinal axis (L). A circlip (48) is arranged axially between the fuel injector (20) and the plate element (38) to prevent a movement of the fuel injector (20) relative to the plate element (38) in a second direction (D2) of the central longitudinal axis (L) opposing the first direction (Dl) of the central longitudinal axis (L).</p>
