Locking claw

A fastening device for a fuel injector in the cylinder head region of an internal combustion engine, in which the fuel injector includes an injector body and is embodied essentially symmetrically to a primary injector axis, the fastening device being embodied as a locking claw, the locking claw having an opening therethrough fitting over the injector body, and at least one detent lug on an inner edge of said opening, wherein the detent lug is embodied as a raised protrusion protruding past the inner edge of the opening, wherein said opening comprises a first opening portion and a second opening portion, the first opening portion being embodied with a diameter which exceeds a diameter of the injector body, and the second opening portion preferably being embodied in slotlike form.

In combination, a fuel injector for an internal combustion engine and a fastening device for fastening the fuel injector in the cylinder head region of the engine, the fuel injector comprising an injector body embodied essentially symmetrically to a primary longitudinal axis, and at least one flat face, and the fastening device comprising a locking claw having an opening therethrough fitting over the injector body, and at least one detent lug on an inner edge of said opening, wherein the detent lug is embodied as a raised protrusion protruding past the inner edge of the opening.
