PROBLEM TO BE SOLVED: To provide a piping connection member being inexpensive by simplifying the piping connection member and by improving its productivity. SOLUTION: The piping connection member comprises an approximate C-shaped pulling-off prevention pin 1 having two symmetrical approximately-bar-shaped leg sections 1a and a trunk section 1b continuous with the leg sections 1a, and a connection hole member 3 having a connection hole 3a. Two approximately-bar-shaped leg sections 1a are fitted in a piping 2 by inserting two approximately-bar-shaped leg sections 1a into the connection hole 3a, the piping connection member can be simplified in a simple shape by connecting the piping 2 and the connection hole member 3, prevention of pulling-off for the pin 1 can be prevented by firmly fixing the pulling-off prevention pin 1 on the piping 2, manufacturing man-hours of the pin 1 can be reduced in the simple shape, and the inexpensive piping connection member can be provided by improving its productivity.
