Abstract: A supporting and bracing element is disclosed for engaging an edge of a plate-like unit such as a sealed glazing unit, received by a frame. The supporting and bracing element comprises an elongated disc-shaped body having at least two longitudinally extending edge ribs. At least one loop formation extends between the edge ribs at one of their short sides and also extends perpendicular to the upper- or underside of the edge ribs beyond the thickness of the edge ribs. The loop formation is movable for being jammed between the edge portion of the sealed glazing unit and the surrounding frame bar during the mounting of the sealed glazing unit.
