Apparatuses for immobilizing fuel injection apparatuses are disclosed. A coupling member couples a fuel injection apparatus with an injector body of an engine. The coupling member includes a top surface, a bottom surface, a side surface, and an opening extending from the top surface to the bottom surface. The opening receives the fuel injection apparatus. The coupling member also includes a protruding portion extending from the bottom surface or the side surface which comes into contact with the injector body to prevent rotational movement of the fuel injection apparatus.
