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.

An interlocking joint in which a tongue projecting along an axis from a face of a first member is interlockably engaged within a groove in a second member, said groove comprising: (a) a narrow mouth extending through an outer wall of said second member; (b) a wide aperture extending through said second member parallel to said mouth; (c) sloped surfaces connecting inward edges of said mouth to respective outward edges of said aperture; and said tongue comprising: (d) a narrow segment extending from said first member; (e) a wide segment extending from said narrow segment, said wide segment having a pair of inward edges projecting laterally on two sides of said narrow segment to constitute a pair of opposed shoulders facing said face of said first member; wherein said sloped surfaces act as ramps to draw said shoulders into said groove away from said face of said first member and to thereby tension said narrow segment when said tongue is rotated about said axis between a disengaged position in which said wise segment is substantially inside of and parallel to said mouth and an engaged position in which said wide segment is generally perpendicular to said mouth.
