Abstract: A panel connector for interconnecting and supporting panels along their side edges to form space divisions. The panel connector comprises a structural connecting post having a supporting bottom end and a securing top end. The connecting post has opposed parallel side walls with a first pair of side walls having hook receiving apertures spaced in groups along the connecting post. A clamp bracket is secured in the top corner of at least one panel to be secured to the connecting post. A clamp is associated with the bracket and has a hooking element which engages with the apertures in the top end of the connecting post and with hook cavities in the clamp bracket to rigidly connect the panel to the connecting post. The side edge of the panel is also provided with a hooking clamp spaced from the top end to engage with further hook receiving apertures provided along the connecting post.
