Abstract
A connector head construction for a high-pressure fuel injection tube comprises a metal tube having a relatively large wall thickness and small diameter and including an abacus-bead-shaped connector head having a front outer peripheral pressor wall for engagement with a mating connector seat and a rear outer peripheral pressure-bearing wall for engagement with a fastening nut on the metal tube. The connector head includes an integral gradual slant surface extending as a skirt from a top of said pressure-bearing wall at an angle ranging from 2.degree. to 5.degree. to the axis of metal tube and having a length equal to at least an outside diameter of the metal tube.
