Abstract: A fitting for detachably interconnecting two walls of an item of furniture at an angle to one another. The fitting comprises a bearing body locatable in one wall, which body has two bores formed therein, a rotatable torsion bolt being located in one bore and a portion of a tightening bolt in the other bore. On its external surface the torsion bolt is grooved. The two bores communicate with one another. In use, the head of the tightening bolt engages with the groove in the torsion bolt, and the opposed end of the tightening bolt engages in the other wall whereby rotation of the torsion bolt locks the tightening bolt in position and causes said walls to be interconnected.
