A pivotal frame connector or pivotal coupler for pivotally attaching two adjacent display structures wherein each of the display structures includes a skeletal frame formed of a network of elongate support rods joined by hub assemblies which provide for articulation of the support rods. The pivotal frame connector includes ends identical in structure to the ends of the support rods to engage those hub assemblies disposed on the periphery of the display frames. These peripheral hub assemblies have empty unused sockets to which the pivotal frame connector is readily attached. The pivotal frame connector is U-shaped and substantially shorter in length than each of the support rods to remain out of sight and out of the way when the display frame is covered by a skin-like aesthetic covering.
