PROBLEM TO BE SOLVED: To provide a socket type pipe joint allowing easy and sure connecting work, even in a narrow working space such as the inside of an instrument. SOLUTION: On a female pipe 2 side, a piping connection fitting 10 is mounted in advance. By pushing a male pipe 1 formed into a tapered shape at an end part into the fitting 10, the male pipe 1 advances, widening the piping connection fitting 10. By engaging the piping connection fitting 10 to the male pipe 1, the male pipe 1 and the female pipe 2 are connected. |
