ABSTRACT:
A joining device for joining first and second board-like furniture parts meeting at an angle, preferably at right angles, with respect to each other, comprising: first and second fittings adapted to be sunk fixedly into first and second mortises respectively in said first and second furniture parts, said first fitting comprising a turn wedge with a snail-shaped locking wedge which is mounted in said first fitting for turning out of a starting position in which it is turned back into the fitting, into a locking position in which it emerges from said first furniture part. The second fitting has in its surface facing the first fitting with the turn wedge, an undercut recess into which the locking wedge can engage. The first and second fittings are in the form of substantially cylindrical plastic drive-in cups adapted to be driven or inserted into the first and second mortises respectively, while the mortises have orifices on one side face of the furniture parts to be joined together. The first mortise is broken-through to an edge of the first furniture part for the passage of the turn wedge, and the first fitting has a flattened portion at its side associated with this break-through such that the flattened portion open for the passage of the turn wedge is approximately flush with the edge when in its proper position of assembly.
