PROBLEM TO BE SOLVED: To provide a pipe joint capable of easily and securely operating the jointing with a small number of parts items. SOLUTION: This pipe joint is formed of an inner core provided with a seal material for holding the water-tightness and a lock arm having elasticity. The inner core is fitted in a corrugated pipe formed of a tubular inner wall and a reinforcing projections wound around the periphery of the inner wall to form a fluid flow passage while maintaining the water-tightness. The lock arm is locked with a core material of the corrugated pipe and the inner core so as to connect the both to each other.
