Befestigungsmittel für lösbare Verbindungen von Platten

摘要

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 means (47'', 48'') protruding from said body and drawn together in a resting position; a cam-type operating element (18) rotatable in said 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 said 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 means (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 said resting position of the spring and said working position of the spring and vice versa.
