<p>PURPOSE:To prevent a hose from being twisted, by providing a first cylindrical member, a second cylindrical member, a sleeve, a cylindrical collet and a locking member, and by arranging the hose between the journal part of the second cylindrical member and the collet, being extended toward a small diameter bore part of the first cylindrical member so as to reduce the diameter of the collet. CONSTITUTION:A pipe joint 21 is composed of a joint body 22 or a first cylindrical member having a large diameter bore 22b, and a core member 24 or a second cylindrical member provided thereto with a journal part 24c having an axial hole 24b communicated with a small diameter bore 22a. A sleeve 26 having an inclined surface part 26 is provided in the large diameter bore 22b, and a collet 28 which can increase and decrease its diameter when it slides in the sleeve 26 is provided. A hose 31 is inserted between the journal part 24c of the core member 24 and the collet 28. When an internal pressure is effected in the pipe joint 21, the collet 28 decreases its diameter so as to fasten the hose 31. As a result, the hose can be fastened to the pipe joint by one step, thereby it is possible to remarkably enhance the working efficiency of piping.</p> |
