PROBLEM TO BE SOLVED: To provide a pipe connection structure that is not complicated, which can be easily installed to a connection end part of a connection member of an armrest member or the like of a pipe chair, and in which the connection member to be engaged in a pipe tube can be easily and strongly installed. SOLUTION: A pipe connection metal 10 is formed of a board that is insertable into a pipe leg 6 of the pipe chair with clearance, and a pair of raised pieces 13 and 13 raised from a circumferential end edge 12a of the board upward, and faced to each other to open outward at least at an upper end, in such a way that the raised pieces form an upwardly U-shaped form. An engagement part 15 is formed on the raised piece, and a lock part 9 is formed on an outer circumferential surface of the connection end part 7 of the connection member 4. The engagement part is engaged with the lock part, and the pipe connection metal is installed on the connection end part, so that at least part of an upper end edge of the pipe connection metal resiliently abuts on an inner circumferential wall of the pipe tube.
