Abstract: To provide a safety joint that can prevent an O-ring from falling off due to an ultra-high pressure hydrogen gas flowing through a flow passage in the safety joint at high speed and from being damaged by a foreign matter coming into contact with the O-ring if the foreign matter is mixed in the hydrogen gas.

Abstract: To provide a safety joint that can immediately shut off a hydrogen gas flow path at the initial stage when a plug (nozzle side member) comes out of a socket (fueling apparatus side member) to prevent release of hydrogen gas. In a safety joint (100, 100-1, 100-2) when the plug (10) is disconnected from the socket (20), a plug side shutoff valve 5 and a socket side shutoff valve 24 close, a mechanism for closing the socket side shutoff valve (24) includes a socket side spring (23) for urging a socket side valve body (25), a socket side rod (22) connected to the socket side valve body (25), and a support member (26, 27, 28) for supporting (mounting) the socket side rod (22), the support member (26, 27, 28) moves, together with the plug (10), to a state that the support member (26, 27, 28) does not support (mount) the socket side rod (22) when the plug (10) is disconnected from the socket (20).
