PURPOSE: A structure for connecting a pipe is provided to improve a constitution of a connecting pipe in order to reduce a number of parts and to reuse the pipe after coupling and disjointing the pipe and a connecting pipe. CONSTITUTION: A connecting pipe(1) is provided with an insert portion(9) in which a pipe(30) is inserted at an end thereof. A cap(2) is screw coupled to an end of the pipe(30), and an insert hole(8) is formed at a center portion of the cap(2). An O ring(7), a pressure ring(34) and a constraint member(32) are inserted subsequently. At a front side of the pressure ring(32), an inward inclined face(35) is formed, the constraint member(32) is formed by winding a strip spring type member in coil shape. After inserting the O ring(7), the pressure ring(34) and the constraint ring(32) to the insert portion(9) of the connecting pipe(1), the cap(2) is coupled loosely to the connecting pipe(1). The pipe(30) is inserted to the connecting pipe(1) through the insert hole(8) of the cap(2) and is coupled hardly.
