ABSTRACT:
A construction element has at least one coupling device and the coupling device has at least two prongs. Each prong is comprised of two radially extending mating surfaces which frictionally engage the radially extending surfaces of a mating coupling device. The construction device may have a straight shaft or an angled shaft to accommodate the needs of the user and, furthermore, the prongs of a coupling device may be inserted within mateable apertures in the shaft of another construction element. Using a plurality of such construction elements, a lattice frame may be constructed.
