FIELD: pipeline transport.
SUBSTANCE: device comprises coupled thin-walled semi-rings secured in the pipe joints and sealing members. The semi-rings are arranged symmetrically with respect to the face wall of the jacket, provided with guides on the mating edges, and have two inner ring grooves. The sealing members are set in the grooves and cooperate with the pipeline by their projecting parts. The sealing members are arranged from the inner and outer sides of the faces of the jacket or adapting rings and define the inner and outer ring seal under the action of the elastic strain force when the detachable members of the jacked are pressed to each other.
EFFECT: enhanced reliability.
