<p>The retainer device, in the building industry, produces rigid connection between the end of one square framework element or other bar-type element, and another running across its end. A seat and/or guideway for one of the two elements (2) is formed by two parallel holder panels (4, 5), rigidly joined by connecting elements (6, 7) running crossways. At the same time they provide between them a through passage opening (9) for the other bar element (1). The connecting units are in the form of stops which check the bar elements from swinging out of line, in at least one direction; there are at least two, facing each other.</p> |
