A torch connector of an oxygen cutter is provided to prevent gas leakage by installing the torch connector, thereby maximizing joining force of the integrated hose and a torch while applying a mutually integrated hose to the oxygen cutter. An oxygen cutter torch connector(100) for preventing gas leakage comprises: a branch port(110) including a main pipe(111) having catching projections(111a) formed in multistage on an outer periphery of one side thereof such that the catching projections are joined with an outer layer inlet of a connecting covering(34c) of an integrated hose(34), and a gas pipe(112) and an oxygen pipe(113) branched off from the other side of the main pipe such that the gas pipe and the oxygen pipe are in communication with the main pipe; connecting units(120) including a bush(123) fitted into an inner periphery of the gas pipe of the branch port, a connector(121) which is penetrated into a hexagonal nut(122) and penetratingly clamped to an inner periphery of the bush, and the connector which is penetrated into the hexagonal nut and directly clamped into an inner periphery of the oxygen pipe such that the respective connectors are joined and communicated with a gas pipeline(31) and an oxygen pipeline(32) formed in the oxygen cutter to supply gas and oxygen from the connectors to the gas and oxygen pipelines without leakage; and joining pipes(130) joined with the connectors of the connecting units, guided to the main pipe along the gas and oxygen pipes, and joined with a gas hose(34a) and an oxygen hose(34b) of the integrated hose respectively.
