The connector is for coupling end to end the bottom flats (2) of two sections (1) having in right angle section the form of a `U' with a wide rectilinear base. It is formed by a rectangular plate (7) with two parallel edges (A) each extended by two flat rectangular successive plates, known as a first plate (8) folded at 180 degs. along the edge (A) under the plate and extending up to an edge (B) parallel to the edge (A), and a second plate (9) folded at 180 degs. along the edge (B) under the first flat (8). The width of the two first plates (8), perpendicular to the edges (A and B), is chosen so that the edges (B) of the two first plates (8) are in juxtaposition.
