When the angle between the outer peripheral part of the ring and the plane perpendicular to the axis is reduced by the diameter expansion action that occurs when the tube to be connected is inserted, and when the pull-out force is applied to the tube. 0 degrees or more and 90 degrees in any case when the diameter increases due to the diameter reduction effect that occurs when
The angle made with the axis of the inner circumference of the ring when the release ring is pushed in to pull out the tube is less than the axis of the inner circumference of the tip of the release ring. A retaining ring for a pipe joint, characterized in that it is set to be approximately at the same angle as the angle made to the line.
