Claim 9:
10. A method of making a hose assembly, the method comprising:
providing a collar including an outer end portion defining an inner radial dog lock, an annular step portion extending radially outward of and axially inward of the dog lock, and an inner end portion extending radially outward of and axially inward from the step portion;
inserting a hose end into the inner end portion of the collar such that an axially outer edge of an outer surface of the hose end abuts an axially inner end of the annular step portion;
inserting a nose portion of a connector body through the outer end portion of the collar and into an inner bore in the hose end portion, such that the dog lock is axially aligned with an annular dog lock groove defined by axially spaced first and second annular flanges in an intermediate portion of the connector body; and
crimping the collar radially inward, such that the dog lock is received in the dog lock groove, the hose end portion is radially compressed between the inner end portion of the collar and the nose portion of the connector body, and an outer surface of the first annular flange and an inner surface of the step portion define an annular radial gap;
wherein inserting the nose portion of the connector body through the outer end portion of the collar and into the inner bore in the hose end portion comprises axially aligning the first annular flange with the annular step portion, with the step portion having an axial width that is greater than an axial width of the first annular flange, such that when the collar is crimped radially inward, the outer surface of the hose end portion is secured axially inward of the first annular flange wherein the annular radial gap is sized to permit limited extrusion of the plastic inner core tube between the first annular flange and the annular step portion, wherein the first annular flange defines a non-tapered side surface of the dog lock groove in mating engagement with an inner radial surface of the dog lock.
