Each clip comprises a flat base having a pair of upstanding opposite side walls with free ends that turn inwardly to form two upper channels which slidably engage and guide the edges of an arm of one member. A corresponding pair of depending opposite side walls are positioned orthogonally to the upstanding side walls in the plane of the base and form a pair of lower channels that slidably engage and guide the edges of a crossing arm of the other member.
