A two-way twin-axial connector module of a receptacle for transporting liquefied gas is provided, including a male connector connected to an end of a transferring pipe incorporating a first supply line for supplying liquefied gas and a first return line for retrieving the vaporized gas, including a pair of male bayonets formed to protrude and surround protruding portions of the first supply line and the first return line, respectively, which are formed to protrude outward through the end of the transferring pipe, and a female connector incorporating a second supply line for supplying liquefied gas and a second return line for retrieving vaporized gas, to be connected to a supply source for supplying liquefied gas or a storage tank for storing liquefied gas, including a pair of female bayonets concavely formed and connecting with the second supply line and the second return line, respectively.

A coupling device and method for cryogenic fluid transport features quick connection, automatic closure, and emergency separation. The device includes two insulated pipes with self-closing valves at their connection ends. A quick-connection mechanism rapidly joins the pipes, while a distinct emergency separation system, located at one pipe's connection end, allows for immediate, safe disconnection in emergencies. This system ensures a rigid link during normal operation and a split configuration upon activation, separating the connection end from the pipe without fluid spillage. The design prioritizes reliable, sealed coupling/uncoupling and minimizes heat transfer, making it suitable for applications like liquid hydrogen.

A thermal protection device includes a cover including a wall, according to a longitudinal axis, with a rear portion adapted to be mounted on the connector so as to surround it at least partially and with a front portion adapted to be mounted on the tubular element and to hold it by a mechanical connection.
