To provide a pipe fitting which allows pipes to be connected easily, allows tightening forces for the connection to be set easily, and prevents its parts from being dispersed.

This pipe fitting includes a movable cylinder 11 provided freely slidably on the inner periphery of a cylinder member 7; a plurality of elastic claw parts 13 each secured at one end to the outer periphery of the movable cylinder 11 and held at a predetermined interval to the movable cylinder 11 at the other end; a fastening member 21 screwed to the cylinder member 7 and on the inner periphery of which a taper part 22 tapering toward a pipe slot 23 is formed; a spring 18 pressing the elastic claw parts 13 against the taper part 22 by exerting an elastic force on the movable cylinder 11; and a stopper 19 preventing the movable cylinder 11 from loosening from the cylinder member 7. When a pipe (b) is connected, the elastic claw parts 13 leave the taper part 22, and the pipe (b) is inserted between the elastic claw parts 13 and the movable cylinder 11, and, by leaving hands from the pipe (b), the elastic claw parts 13 are made to bite into the pipe to fasten the pipe (b).
