A safety device (1), comprising: a main body (2); a flow pipe (4); a sleeve ring (5) fixedly sleeved on the periphery of the flow pipe (4), and one side of the sleeve ring (5) abutting against and making contact with the main body (2); and an elastic member (6) elastically abutting between a connector (31) of a pipeline system (3) and the flow pipe (4). When either of the main body (2) or the sleeve ring (5) is a magnet while the other one is a magnetized object, either of the main body (2) or the sleeve ring (5) is demagnetized or degaussed when being subjected to an external force or a heating temperature of 80°C or more, or the external force separates the two away from a magnetic contact range, the flow pipe (4) is pushed against by the elastic force of the elastic member (6), and the flow pipe (4) is closed by the main body (2), such that a fluid cannot flow through the flow pipe (4), and the safety device (1) switches from an unlocked state to a locked state.
