A hose construction as set forth in claim 1 wherein said projections of said inner hose and said insert means are respectively annular and are respectively disposed substantially transverse to the longitudinal axis of said hose construction. 3. A hose construction as set forth in claim 1 wherein said projections of said inner hose and said insert means respectively extend in a helical path about the longitudinal axis of said hose construction. 4. A hose construction as set forth in claim 1 wherein said inner tubular metallic sleeve has an outer peripheral surface means provided with outwardly directed projections with recesses therebetween and wherein said outer tubular polymeric sleeve has an inner peripheral surface means provided with inwardly directed projections with recesses therebetween, said projections of said inner tubular metallic sleeve being respectively received in said recesses of said outer tubular polymeric sleeve and said projections of said outer tubular polymeric sleeve being respectively received in said recesses of said inner tubular metallic sleeve. 5. A hose construction as set forth in claim 4 wherein said outer tubular polymeric sleeve is molded onto said inner tubular metallic sleeve. 6. A hose construction as set forth in claim 4 wherein said outer tubular polymeric sleeve remains separate from said inner tubular metallic sleeve until said insert means has been radially outwardly expanded. 7. A hose construction as set forth in claim 1 wherein said tubular hose has an outer peripheral surface means, said coupling having an outer metallic tubular member telescopically disposed over said tubular hose and being engaged by said outer peripheral surface means of said tubular hose. 8. A hose construction as set forth in claim 1 wherein said coupling has a rotatable nut means for fluidly coupling said hose construction to other structure. 9. In a method of making a hose construction comprising the steps of forming a tubular hose having an inner peripheral surface means and an outer peripheral surface means, and securing a coupling to one end of said tubular hose, the improvement comprising the steps of forming said inner peripheral surface means of said tubular hose to comprise an inner corrugated hose made of polymeric material and having inwardly convex projections with recesses therebetween and extending from said one end of said tubular hose to the other end thereof, forming said coupling to have an insert means disposed in said one end of said tubular hose and be radially outwardly expanded into sealing relation with said inner corrugated hose, forming said insert means to have an outer peripheral surface means defined by a plurality of outwardly convex projections with recesses therebetween, and forming said projections of said insert means to be respectively received in said recesses of said inner hose and said projections of said inner hose to be respectively received in said recesses of said insert means whereby the interior of said tubular hose is substantially sealed to the interior of said coupling, forming said insert means to comprise an inner tubular metallic sleeve and an outer tubular polymeric sleeve telescopically disposed on said tubular metallic sleeve and having an outer peripheral surface means that comprises said outer peripheral surface means of said insert means, and simultaneously radially outwardly expanding said inner tubular metallic sleeve and said outer tubular polymeric sleeve in the telescoped relation thereof to provide said sealing relation with said inner corrugated hose. 10. A method of making a hose construction as set forth in claim 9 and including the step of forming said projections of said inner hose and said insert means to be respectively annular and to be respectively disposed substantially transverse to the longitudinal axis of said hose construction. 11. A method of making a hose construction as set forth in claim 9 and including the step of forming said projections of said inner hose and said insert means to respectively extend in a helical path about the longitudinal axis of said hose construction. 12. A method of making a hose construction as set forth in claim 9 and including the steps of forming said inner tubular metallic sleeve to have an outer peripheral surface means provided with outwardly directed projections with recesses therebetween, forming said outer tubular polymeric sleeve to have an inner peripheral surface means provided with inwardly directed projections with recesses therebetween, and forming said projections of said inner tubular metallic sleeve to be respectively received in said recesses of said outer tubular polymeric sleeve and said projections of said outer tubular polymeric sleeve to be respectively received in said recesses of said inner tubular metallic sleeve. 13. A method of making a hose construction as set forth in claim 12 and including the step of molding said outer tubular polymeric sleeve onto said inner tubular metallic sleeve. 14. A method of making a hose construction as set forth in claim 12 and including the step of forming said outer tubular polymeric sleeve to remain separate from said inner tubular metallic sleeve until said insert means has been radially outwardly expanded. 15. A method of making a hose construction as set forth in claim 9 and including the steps of forming said tubular hose to have an outer peripheral surface means and forming said coupling to have an outer metallic tubular member telescopically disposed over said tubular hose and be engaged by said outer peripheral surface means of said tubular hose. 16.
