PURPOSE: An L-type nipple is provided to adhere closely a hose part to a sub tightfitting portion, thereby preventing the inflow of the air to the inside of the hose or the outflow of a pressure medium to the outside of the hose. CONSTITUTION: One front end of a bent portion(130) is expanded from the other front end of a pressure portion(110) coaxially. The other front end of the bent portion is bent at a predetermined angle for the coaxial direction. A hose tightfitting portion(143) is expanded than a band fixing portion(141) to form a step with the band fixing portion. The external diameter of the hose tightfitting portion is reduced toward a free tip to form an inclined surface. The sub tightfitting portion is arranged in the front end of the bent portion side of the band fixing portion. The sub tightfitting portion is expanded than the band fixing portion form a step with the band fixing portion. The external diameter of the sub tightfitting portion is gradually reduced toward the bent portion to form an inclined surface.
