    • 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.
    • 为了提供一种通过电动工具或人力添加的旋转力的损失明显减小的管接头,并且能够以小的扭矩减小紧固环,多个紧固环6以360°至480°的预定中心角垂直缠绕 °,引导构件8,其保持紧固环6,以限制紧固环6的下落,并且允许减小变形;大致三角形的肘节构件11,设置成沿管道未连接状态从紧固环6沿径向外侧方向突出; 以及用于使肘节构件11的中心峰部沿径向内侧方向移动以减小肘节构件11的高度尺寸的螺栓 - 螺母连接X. 紧固环6具有在径向外侧方向上突出的钩挂爪部7,并且肘节构件11的与脚蹬爪部7连接的脚侧端部沿圆周方向移动,以将紧固环6缩小 直径。
