FIELD: machine building.
SUBSTANCE: fitting 10 includes a hollow body 12, a sealing link 44, and a traction mechanism. Fitting mechanism includes a main actuator 20 connected to a body 12 at the first end 22 and a plurality of auxiliary actuators 50 connected to the sealing link 44. A plurality of auxiliary actuators 50 are arranged in the inner space of the hollow body 12 and are spaced circumferentially from each other. A plurality of auxiliary actuators 50 also engage with the main actuator 20 so that actuation of the main actuator 20 lifts a plurality of auxiliary actuators 50 axially towards the hole at the first end 22 of the hollow body 12, thereby moving progressively the sealing link 44 from the open position to the sealing position.
EFFECT: simplified assembly, higher reliability of connection.
