PURPOSE: A connection pipe having branch pipe opening/closing structure is provided to easily apply a valve by individually preparing respective members and directly installing a shutoff valve in the branch pipe of a T-shaped connection pipe and to secure precision in opening and closing motion by directly applying a valve structure to a connection pipe having durability and firmness. CONSTITUTION: A T-shaped connection pipe(1) is formed perpendicular to a linear main pipe(2) having an inlet(2A) and an outlet(2B). The connection pipe is constituted of a branch pipe(3) having a path communicated with the inside of the main pipe. To selectively open and close the path of the branch pipe, a shutoff valve(4) is included. The shutoff valve consists of a spherical valve body having a communication hole and a handle(4D) combined with the valve body via a threaded connection bar(4C).
