Abstract: Coupling means, for example for use in the furniture industry, comprises a body member having a threaded opening which communicates with an internal cavity; an elongate headed member, a shank portion of which is receivable through a slot formed in the side of the body member with its head retained within the cavity; and a threaded member receivable in the threaded opening and adapted to bear against the head of the headed member. The interior of the cavity is so shaped that tightening of the threaded member in the opening is arranged to draw the shank of the headed member further through the slot into the interior of the cavity.
