摘要： To provide a pipe joint with which loss of rotational force added by electric tools or man power is made remarkably small, and a fastening ring can be diminished with small torque, plural fastening rings 6 vertically wound for a predetermined center angle of 360° to 480° , a guiding member 8 holding the fastening rings 6 as to restrict falling of the fastening rings 6 and allow diminishing deformation, an approximately triangular toggle member 11 disposed to protrude in a radial outer direction from the fastening rings 6 in a pipe unconnected state, and a bolt-nut connection X for moving a central peak portion of the toggle member 11 in a radial inner direction as to reduce a height dimension of the toggle member 11, are provided. The fastening ring 6 has a hitching claw portion 7 protruding in the radial outer direction, and a foot side end portion of the toggle member 11, hitching to the hitching claw portion 7, moves in a peripheral direction as to diminish the fastening ring 6 in diameter.
