Abstract: Attachment member adapted to be mounted on supports or load-bearing elements of the type of ribbed sheet metal. It includes a tubular body (2) provided with connection structure (3) and an anchoring element (4, 5) on one of the ends of the tubular body (2) and extending perpendicularly relative to this latter. The anchoring element is made up of a straight rod portion (4) and an elbowed rod portion (5), of L shape, disposed on opposite sides of the tubular body (2). A plate (13) has a central connector (14) that screws into the connection structure (3) to retain insulating panels (15). A sealing sheet (16) is adhesively secured to the plates (13) and insulating panels (15).
