ABSTRACT:
An attachment clip for connecting a top-feed fuel injector to a socket on a fuel rail has a cylindrical wall that is coaxial with the fuel inlet tube of the injector and contains a pattern of circumferentially spaced apertures. At each aperture there is at least one catch that extends from the margin of a circumferentially extending edge of the aperture radially inwardly and axially toward the fuel injector body to terminate at a distal end that is axially within the axial span of the aperture. The circumferential span of each catch is less than that of the aperture. As the fuel inlet tube is pushed into the socket, the catches are resiliently flexed by engagement with the socket rim until the distal ends of the catches clear a lip extending around the outside of the rim at which point they relax to lodge behind the lip thereby attaching the fuel injector to the socket.
