FIELD: machine building.
SUBSTANCE: invention relates to a coupling, which has first and second segments attached to each other butt-jointing, surrounding central space for receiving of tubular elements. Spring assembly secures the segments at one end, and the adjustable fastening assembly secures the segments at the opposite end. Spring assembly displaces segments from each other sufficiently to allow insertion of tubular elements into central space when segments are attached to each other. Coupling may comprise toothed holder in form of split ring for connection of pipe elements with smooth ends or may have arched locks engaged with grooves or flanges of pipe elements.
EFFECT: invention simplifies connection assembly process.
