The present invention provides an improved modular system for constructing a tubular structure. The improved system allows the tubing to be assembled and disassembled in a direction perpendicular to a centerline of the tubing without having to move the tubing along its centerline. The improved system allows the tubing to be positioned at various angles. The system also enables curved tubing to be used. In an embodiment, the structural system includes a hub and a connector that removably couples to the hub. The connector has a first end that couples to the hub and a second that defines a notch. One of the walls of the notch connects to a flange that may extend in one or two directions from the centerline of the connector. The connector and flange removably couple to one end of an adapter, which contains a mating notch, wherein the adapter receives a tube.
