A coupling device (1) for connecting two bars (2) of a frame extends along an axis (X) between two axial ends (13, 14), respectively provided with an insert portion (15), insertable inside a first bar (2); and with a fastening portion (16), adapted to hook on a lateral wall (8) of a second bar (2), to be joined perpendicularly to the first bar (2); the coupling device (1) comprises a support body (17); a leaf spring (18) elastically deformable and supported by the support body (17); and a control member (19) rotating about the axis (X) and acting on the leaf spring (18) via a cam (59); the rotation of the cam (59) elastically pushes the leaf spring (18) so as to move in opposite directions respective end portions (51, 52) of the leaf spring (18) for blocking the insert portion (15) inside the first bar (2), and for hooking the second bar (2). |
