Abstract
A coupling for suspending a fuel injector from a fuel rail assembly of an internal combustion engine includes a collar that mates with the fuel injector and a retainer clip that engages with the collar thereby mechanically connecting the fuel injector to the fuel rail assembly. The retainer clip includes windows to enable even load distribution upon the socket flange when assembled. Features are integrated in the collar to facilitate correct alignment of the injector relative to the fuel rail. Paired together, the retainer clip and the collar enable a secure, and a keyed fuel injector-to-fuel rail connection that is able to withstand high pressure separating loads.
