  "textContent": "Coupling device (50) for coupling a fuel injector (20) to a fuel rail (14) of a combustion engine (22). The coupling device (50) comprises a fuel injector cup (30), a first flange (36), a second flange (38), a shell element (44, 45) and a fixing element (54). The fuel injector cup (30) has a central longitudinal axis (L) and is designed to be hydraulically coupled to the fuel rail (14) and to engage a fuel inlet portion (24) of the fuel injector (20). The first flange (36) is fixedly coupled to the fuel injector cup (30) and the second flange (38) is fixedly coupled to the fuel injector (20). The shell element (44, 45) comprises a first projection (44a, 45a) and a second projection (44b, 45b). The flanges (36, 38) are axially arranged between the first projection (44a, 45a) and the second projection (44b, 45b), and the shell element (44, 45) is designed and arranged in a way that the flanges (36, 38) are in mechanical cooperation with the shell element (44, 45) to retain the fuel injector (20) in the fuel injector cup (30) in direction of the central longitudinal axis (L). The fixing element (54) is arranged on a circumferential outer surface (52) of the shell element (44, 45) and is designed to prevent a radial movement of the shell element (44, 45) relative to the flanges (36, 38). The fixing element (54) comprises a radially spring-loaded element (46) which is arranged and designed in a manner that the spring-loaded element (46) is in engagement with a recess (47) in the shell element (44, 45) to prevent an axial movement of the fixing element (54) relative to the shell element (44, 45).",
