METAL CONNECTING DEVICE FOR HOSE

摘要

PURPOSE: A metal connecting device for a hose is provided to improve the contact area by forming a molded part of a sleeve and a bead molded part in the direction of contacting to a hose when molding a sleeve. CONSTITUTION: A metal connecting device is composed of a pipe(10) for a nipple inserted to a hose and a sleeve(40) formed coaxially with the pipe. Front and rear beads(30,30-1) are formed on the combining part of the pipe when combining the pipe to the sleeve. A hose(60) is inserted to the sleeve having annular protrusions(50) in the inner face in a straight line to be correspond to the rear bead of the pipe for nipple. Thereby the contact area on the face of the side part of the hose, the bead face of the pipe and the face of the annular protrusion get bigger when forcibly inserting the hose to the sleeve.
