Improved construction sets, consisting of bars of right-angled cross section, characterized by each side or wing of the bar contains a series of grooves in the form of a right angle, separated along the length of the wings, with their vertices directed alternately in the opposite direction transversely to the length of the bar; said grooves are arranged in such a way that when two of said elements are placed at right angles to each other, there is always sufficient overlap of the angular grooves to form at least one fixing hole of diameter equal to the width of the groove.
