The invention concerns a coupling device (40) for mechanically coupling a fuel rail (18) to a cylinder head (70) of a combustion engine (22). The coupling device (40) comprises a fuel injector cup (30) being designed to be hydraulically and mechanically coupled to the fuel rail (18) and being arranged and designed to face the cylinder head (70), a first fastening element (48) facing the fuel injector cup (30) and being designed to be fixedly coupled to the cylinder head (70), at least one first spring element (50, 52) being arranged between the first fastening element (48) and the fuel injector cup (30) and/or being arrangeable between the fuel injector cup (30) and the cylinder head (70), a support element (56) being arranged between the fuel rail (18) and the cylinder head (70) and being designed to be fixedly coupled to the fuel rail (18), a second fastening element (58) being in engagement with the support element (56) and being designed to be fixedly coupled to the cylinder head (70), and at least one second spring element (60, 62) being arranged between the second fastening element (58) and the support element (56) and/or being arrangeable between the support element (56) and the cylinder head (70). The at least one first spring element (50, 52) consists of a metal or comprises a metal, and the at least one second spring element (60, 62) consists of a plastic or comprises a plastic.
