FIELD: instrument engineering.
SUBSTANCE: invention relates to a connector for connecting two fluid circuits comprising two connectors (2), each of which is configured to be installed in one of these circuits (1). Each connector comprises nozzle (4) configured to cooperate with a connector of another connector to form a fluid passageway between the connectors, first valve (7) and second valve (7) located in these nozzles and capable of segregating or opening the internal volume of the corresponding branch pipe selectively and hermetically, and in the internal volume of each branch pipe there is buffer space (16), bounded by the inner wall of this branch pipe, first valve and a second valve, first actuator (8) of the first valve and second actuator (9) of the second valve. Coupling device also comprises connecting element (13) capable of sealingly coupling the pipes of both connectors.
EFFECT: invention improves joint reliability.
