Abstract: A clip for securing the inlet of a fuel injection nozzle within a tubular outlet extending from a petrol supply manifold has a pair of spaced side plates which are interconnected by a bridging member. The side plates have internal ears which locate in slots on opposite sides of the injector, slots in the side plates which receive a rim on the tubular outlet. The side plates are extended to define tongues which extend into engagement with the surface of the manifold to locate the clip and therefore the injector in a predetermined angular relationship in the tubular outlet.
