The toy construction elements include a rectangular fastener having a hinge which extends diagonally across the fastener and which divides the fastener into two triangular segments. A connector is associated with each segment. The other construction element is a polygonal body having an upper section a nd indented sections equal to the number of sides of the polygon. Each indented section is triangular and has an outer edge defined by one side of the polygon and a pair of inner edges which extend inward from the outer edge and intersect at their inner ends. Each indented section is provided with a connector which is complementary with the connector of the fastener such tha t each segment of the fastener may be fastened face-to-face with each indented section of the polygonal body.
