FIELD: technological processes.
SUBSTANCE: pipe joint has first clutch 10 connected to first pipe 1 and second clutch 20 connected to second pipe 2 and having an open part that can cover first clutch 10. First clutch 10 has first ring 11, second ring 12 and third ring 13 having the internal diameter d13 larger than the outer diameter D12 of second ring 12 and supported by both walls 12tw of groove 12t formed by first ring 11 and second rings 12 and others with the ability to rotate about an outer circumference. Third ring 13 has at least one first projection 14 projecting outward in a radial direction. On the other hand, second clutch 20 has notch 21 receiving first projection 14 and first recess 22 receiving first projection 14 from said notch 21 and guiding it rotatably along an inner circumference of second clutch 20.
EFFECT: pipe joint is proposed that allows to improve controllability and facilitate the repair of elements, damaged during pipe being connected or maintenance of the pipeline.
