PROBLEM TO BE SOLVED: To prevent an unexpected connection release and noise generation of a connecting device in an installation structure. SOLUTION: This connecting device in the installation structure is constituted so that a circular arc-shaped recessed part 10 is formed on both side rear surfaces of a central wall 5 of a bracket 2; a pair of rotary bodies 11 are arranged on both sides of a horizontal projection part 8 of a locking metal fitting 4; the rotational axis 12 is penetrated through the horizontal projection part 8 via an elongate hole 13; a front projection part 14 having the circular arc edge 14a freely going in and out along its circular arc surface 10a, is formed in both side recessed parts 10 of the central wall 5 by the rotational movement; and a rear projection part 15 equal to a horizontal distance between a point O2 separate downward by a predetermined distance D from the center O1 and a front face of an end surface plate 7, having the circular arc edge 15a of a radius R1 with this separate point O2 as the circular arc center and freely separating from and coming into pressure contact with the end surface plate 7 by the rotational movement, is formed on a vertical line V passing through the center O1 of the rotational axis 12.
