PURPOSE: A bidirectional pipe connector using an expansion protrusion is provided to minimize the number of parts for connection with a bellows pipe. CONSTITUTION: A bidirectional pipe connector comprises a first horizontal part(10) of cylindrical shape which has a specific inner diameter so that a bellows pipe is inserted, an expansion protrusion connection part(13) formed along one side inner circumference of the first horizontal part, an expansion protrusion(14) which is formed wider than the expansion protrusion connection part and has pipe insertion spaces(15), an inclined part which is formed integrally with the first horizontal part to be expanded at the fixed angle from both ends of the first horizontal part, and a second horizontal part(12) which is formed integrally with the inclined part.
