FIELD: mechanical engineering. SUBSTANCE: body of joint is made in form of hinge with ends of different length: shorter end of hinge is bent aside and is made in form of additional hinge; longer end of hinge is made in form of turns of spiral embracing the flexible member. One end of flexible member is passed through additional hinge and is rigidly connected with shorter end of hinge. Free end of flexible member is rotated along turns of spiral. Hinge of body is closed. Additional hinge may be made open. Turns of spiral on longer end may be located in a spaced relation. Additional hinge is located coaxially relative to turns of spiral. Additional hinge may be made closed and external diameter of additional hinge may exceed inner diameter of spiral turns. Bend of shorter end of hinge is made in form of bulge.
