A joint of the type made between two elongated frame members and including also a connector member releasably coupling the two frame members tightly one against the other. This joint is characterized by its exclusion of special machining and construction of the components, by the connector member being unconspicuously concealed and by the possibility of assembling one frame member in any angular relationship about its longitudinal axis relative to the other frame member.
