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 outgas. A safety joint (100, 100-1) of the present invention includes: a plug (10) with a flow path (1A) formed inside, a shutoff valve (5) of the plug (10) opens when connected to a socket (20); and the socket (20), a flow path (21A) in communication with the flow path (1A) is formed when connected to the plug (10); and when the plug (10) is disconnected from the socket (20), the flow paths (1A, 21A) of the plug (10) and the socket (20) are shut off, wherein the socket has an opening (21C) that communicates with the flow path (21A) and extends orthogonally to the flow path (21A); when the plug and the socket are connected, a protruding portion (3) of the plug is inserted into the opening; and a socket flow path blocking mechanism (30, 31) is provided to instantly close the flow path (21A) at an initial stage when the plug is disconnected from the socket.
