A connection device for the realisation of a tubular-frame structure for supporting surfaces constituted by a body (18) from which projects at least one socket (19) for connecting to tubular profiles (15) and possibly, in a generic perpendicular direction or at an angle, projects a connector (20) for the removable connection of a leg (14), in which said at least one socket (19) has a non-continuous external wall (21), which defines a seat (22), attached at the base by an abutment surface (42) for a blocking means, with a threaded hole (25) which houses an operation grain (23). <IMAGE> |
