FIELD: transport.
SUBSTANCE: coupling contains two elements (2,3) with annular flanges (13) on ends. Coupling elements are clutch-connected by ends with each other, clutch containing two arched parts (9) each of which have inner cavity (15) made between two bulges directed inside (14) with cavity limited by bottom and two opposite lateral surfaces whether inclined or conical. One of coupling elements in addition to first flange (13) with first shoulder surface has second flange (13') distanced from first flange in axial direction and having inclines second shoulder surface. Forces transmitted via two similar inclined side surfaces on arched parts are distributed over two said shoulder surfaces on coupling element in axial sequence of forces near outer side of element.
EFFECT: easy coupling device is secured.
