The invention relates to the assembly of frameworks for furniture, display shelves, scaffolding, etc., allowing rapid mounting and dismounting of elements, even if rotationally fixed, with a minimum risk of damage, and modest cost price. According to the invention, the framework elements 1, 2 include, at their end, parts 111, 121 which are threaded in opposite directions and are intended to mesh with end parts 31, 32, which are also threaded in opposite directions, of the assembly component 3, which is suitable for being rotationally actuated by turning a spacer roundel 4, which allows assembly of the unit and clamping of the spacer roundel 4 between the two framework elements 1, 2. <IMAGE>
