Summary:Coupling device (60) for hydraulically and mechanically coupling a fuel injector (20) to a fuel rail (14) of a combustion engine (22), the fuel injector (20) having a central longitudinal axis (L). The coupling device (60) 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 (36) being designed to be coupled to the fuel injector (20) and being fixedly coupled to the fuel injector cup (30) to retain the fuel injector (20) in the fuel injector cup (30) in direction of the central longitudinal axis (L), wherein the plate element (36) comprises a groove (32), and a snap ring (42) being arranged in the groove (32) of the plate element (36) and being designed to fixedly couple the plate element (36) to the fuel injector (20). The plate element (36) comprises a main body (38) and a ring element (40). The ring element (40) comprises the groove (32) and is at least limited rotatable around the central longitudinal axis (L) relative to the main body (38) of the plate element (36).
