A simple joint is disclosed for detachably connecting structural members. The connection is made with a resilient T-shaped tongue on a first member which can be engaged in a T-shaped slot on a second member. The tongue is engaged in the slot by rotating it about its axis. Rotation of the tongue causes the end of the tongue to be drawn into the slot by wedging action between the tongue and sloped inner surfaces of the slot. The first and second members are held tightly together by tension which is developed in the tongue as the tongue is drawn into the slot. The invention is well adapted for use in many fields which require parts to be detachably connected to one another such as constructing panel display systems, building modular cabinets or shelving units and building modular furniture.
