Abstract
A coupling device for mechanically and hydraulically coupling a fuel injector to a fuel rail of a combustion engine is disclosed. The coupling device includes a fuel injector cup having a central longitudinal axis and extending from an inlet side for hydraulically coupling to the fuel rail and an outlet side for engaging a fuel inlet portion of the fuel injector, and a collar element coupled to the fuel injector cup. The collar element includes at least one leg portion having a bridge section and at least one branch section extending radially away from the fuel injector cup. The branch section(s) are arranged radially outwardly of the bridge section and project beyond the bridge section in both (b) a tangential direction perpendicular to the radial direction and perpendicular to the longitudinal axis and (b) a longitudinal direction parallel to the longitudinal axis.
