HOSE JOINT

WIPO Patent Application WO/2011/027766

A1

Provided is a hose joint by which an insertion position of a front end of a hose is stabilized to thereby enhance the sealing efficiency and a disconnecting strength between the outer surface of a nipple and the hose. When the hose (H) is inserted, the inner diameter of an inlet portion (3a) of an expandable and contractible sleeve (3) opposed to a decreasing diameter portion (1a2) is set to be larger than the outer diameter of the hose (H) which is inserted along the decreasing diameter portion (1a2) of a bulged portion (1a), whereby the front end of the hose (H) is smoothly introduced between the expandable and contractible sleeve (3) and the decreasing diameter portion (1a2) without causing the front end of the hose to butt against the inlet portion (3a) of the expandable and contractible sleeve (3) and can be inserted to a predetermined position. Thereafter, when pressed by a pressing surface portion (2b) in accordance with the axial movement of a fastening tool (2), the inner diameter of the inlet portion (3a) of the expandable and contractible sleeve (3) is set to be smaller than the outer diameter of the hose (H) inserted along the decreasing diameter portion (1a2) of the bulged portion (1a), whereby the hose (H) is held between the inlet portion (3a) of the expandable and contractible sleeve (3) and the decreasing diameter portion (1a2) of the nipple (1).
