A composite hose with a corrugated metal tube has a hose body having a corrugated metal tube and an outer layer. The corrugated metal tube includes a non-corrugated straight-walled portion on an end portion thereof, and a rigid insert pipe is inserted in the straight-walled portion. A socket fitting is fitted on the hose body by being swaged thereon radially inwardly, and an inner circumferential end portion of the collar portion and an outer circumferential surface of the insert pipe compress an extending portion of the straight-walled portion to fix the straight-walled portion onto the insert pipe and provide a seal between the outer circumferential surface of the insert pipe and an inner circumferential surface of the straight-walled portion. A fracture preventing mechanism is provided on a hose end portion for preventing fracture of the straight-walled portion.
