Abstract: The invention relates to an anti-rotation device of a fuel lance arranged in a bore extending through a cylinder head of a cylinder head from an intake opening until a hole provided for receiving a fuel injector, the lance allowing high-pressure fuel to circulate from an intake opening of the lance until the outlet opening of the lance engaging with the intake opening of the fuel injector, the fuel lance including a nut for being screwed into the intake opening of the bore and a tubular member compressed between the nut and the injector, the lance also including the anti-rotation device. The anti-rotation device is a resilient element which is deformed by rotation of the nut, such as to be blocked between the tubular member and an inner wall of the bore, and thus prevent rotation of the tubular member when the nut is screwed.
