PROBLEM TO BE SOLVED: To provide a connecting device generating no noise when assembling and disassembling a steel pipe structure, capable of visually confirming a nonslip state, while surely providing the nonslip state of an insertion piece to a socket and remarkably improving strength and safety of the steel pipe structure. SOLUTION: In this connecting device 1, the cylindrical socket 4 is arranged on a column 2, and the insertion piece 5 is arranged in an end part of a cloth material 3, and the column 2 and the cloth material 3 are joined by inserting the insertion piece 5 into the socket 4. A nonslip locking metal fitting 10 to the socket 4 is pivoted on a lower end part of the insertion piece 5, and the locking edge 14 eccentric with a pivotal point as the center, is arranged in a cam part 11 of this locking metal fitting 10. This locking edge 14 separates the locking metal fitting 10 from the lower edge of the socket 4 in a position capable of extracting the insertion piece 5 from the socket 4, and is formed so as to act on the lower edge of the socket 4 in a locking position of the locking metal fitting 10 to the socket 4.
