FIELD: pipe line engineering. SUBSTANCE: facility for connecting and disconnecting openings male and female parts is constructed as two couplings. Each of the couplings is mounted on the rotation surface of the male and female parts for permitting rotation about it between one end piston, respective to the connection of the openings and the other position respectively the disconnecting of the pipes. The locking unit prevents against disconnection of the parts in the moment of opening connection. The clamping mechanism serves for interengaging the opens and creating preliminary efforts for their connection. The clamping for maintaining the initial part separation is used for washing with jets which are in coincident with their parts for washing stream fluid jet. EFFECT: enhanced reliability. 9 cl, 12 dwg
