Abstract

A fastening device to join together panels comprises a body (12) that has a spreader (32); a U-shaped spring (14) with arms (47, 48) provided with outward facing gripping portions (47", 48") protruding from the body and drawn together in a resting position; a cam-type operating element (18) rotatable in the body. By rotating the cam element, the spring is movable between a resting position with the arms close to each other, in which it leaves the panels free and an engagement position with the arms spread apart, in which it engages the walls of a hole in a panel, and vice versa. The body (12) has an elongated cylindrical shape and comprises an internal housing (26). A slide element (16) is received inside the housing, is moveable for an axial distance along it, and has a housing (44) for engaging the spring. The cam element (18) is received in the body and in the slide to operate the movement of the slide between the resting position of the spring and the working position of the spring and vice versa.
