Abstract

PURPOSE:To remove a piping easily by composing a pipe joint in the condition a ball body can drop in a recess formed on the peri pheral surface of a movable small tube by pushing in the piping to connect in a specific scope. CONSTITUTION:In a tube body 5, a taper 51 to reduce the diameter toward the opening side is provided, and its opening end is used as a piping insertion port 52 to connect a piping H. A holding tube 3 is set a little larger than the piping inserting port 5 at its outer diameter, and furnishes a slit 30 to open to the piping inserting port 52 side and a slit 33 to open to the other side alternatively. And a clearance between a movable small tube 2 and the holding tube 3 is set a little smaller than the thickness of the piping H to insert therein. Furthermore, a round groove 22 to which a ball body 4 is dropped in to be dropped under the peripheral surface of a main body 1 when the piping H is pushed in a specific scope against the enforcing power to a pressing body 6 is provided to the movable small tube 2. As a result, a pipe joint which facilitates not only contacting the piping but also removing the piping easily can be obtained.
