Abstract
Coupling device for hydraulically and mechanically coupling a fuel injector to a fuel rail of a combustion engine. The fuel injector has a central longitudinal axis. The coupling device has a fuel injector cup being designed to be hydraulically coupled to the fuel rail and to engage a fuel inlet portion of the fuel injector, a first plate element being fixedly coupled to the fuel injector cup, the first plate element comprising a recess, and a second plate element being fixedly coupled to the fuel injector and being arranged in the recess and being fixedly coupled to the first plate element to retain the fuel injector in the fuel injector cup in direction of the central longitudinal axis. The fuel injector comprises a groove. A snap ring is arranged in the groove of the fuel injector and is designed to fixedly couple the second plate element to the fuel injector.
