ABSTRACT:
A rod for a construction set includes an elongate strut that extends between opposed of interconnected joint elements. A cavity in each end of the strut slidably supports a clip having opposed inwardly deflectable fingers, with outwardly facing catches at their extremities, that snap fit into the joint openings in the joint element to clamp the joint element between the catches and the ends of the rods. The clips are moveable between closed positions where the fingers are engaged in the joint elements and open positions where the fingers are located completely within the cavity to allow the rod to be removed from opposed joint elements in a structure without disturbing the structure. The struts have slots in their extremities that intersect the cavities, and the fingers have protrusions that extend through the slots to facilitate deflecting the fingers inwardly to release the clips from the joint elements and in moving the clips between their open and closed positions. The lips on the catches, that contact the joint elements, have chamfered side and front edges to allow rotation of the rod relative to the joint element when it is being removed from the joint element in order to reduce the occurrence of bending moments in the clips that can cause breakage.
