To provide a safety joint capable of preventing moment generated by swinging of a filling hose and surely separating the safety joint to a hydrogen filling apparatus side member and a vehicle side member when a tensile force more or equal to a predetermined value is applied to the filling hose. The safety joint 100 according to the present invention includes a plug (10: vehicle side member) with a cylindrical shape in which a passage (1A: in-plug passage) is formed, a socket (20) in which a passage (21A: in-socket passage) continuing to the passage (1A) in the plug (10) is formed, and a shut off valve mounted on the passage (21A: in-socket passage) in the socket (20), the shut off valve opening when the plug (10) being inserted into the socket (20) and closing when the plug (10) being disconnected therefrom, wherein central axes of the passages of the plug and the socket do not form a straight line (but those are orthogonal with each other for instance), a filling hose (61) is connected to the plug (10), and a hose guide (70, 70A) for limiting movement of the filling hose (61) at a position separated from the plug (10).
A safety joint comprising a plug with a cylindrical shape in which a passage is formed, a socket in which a passage continuing to the passage in the plug is formed, and a shut off valve mounted on the passage in the socket, the shut off valve opening when the plug being inserted into the socket and closing when the plug being disconnected therefrom, wherein central axes of the passages of the plug and the socket do not form a straight line, a filling hose is connected to the plug, and a hose guide configured to allow the filling hose to extend therethrough for limiting movement of the filling hose at a position separated from the plug, the hose guide including an outer cylinder, an elastic member for surrounding the filling hose, an elastic member accommodating portion accommodating the elastic member in a hollow portion, and a lid portion engaging with the elastic member accommodating portion to close the hollow portion, and an inner diameter size of the outer cylinder is larger than a maximum diameter of the plug.
