ABSTRACT:
A fuel hose breakaway unit comprising couplers that are held in assembled relation by longitudinally extending fingers that are mounted on the outlet coupler and engage abutment lugs on the inlet coupler. When a predetermined longitudinal separation force is applied to the couplers, the fingers flex outwardly to a release position, permitting the couplers to separate. The fingers are provided by finger sets, each of which is provided with three fingers. A locking collar locks the bases of the finger sets onto the outer surface of the housing for the outlet coupler.
