Abstract: A guide ring of a sanitary spout fitting having a swivelling spout which can be fitted swivellably on a fitting body via a swivelling sleeve which forms part of the swivelling spout, has material projections on both cylindrical faces. Through these material projections the guide ring is in contact both with the inner cylindrical surface of the swivelling sleeve and with the outer cylindrical surface of the fitting body. The guide ring thus ensures good radial guidance of the swivelling sleeve of the swivelling spout on the fitting body. Because the guide ring can rotate with respect both to the swivelling sleeve and to the fitting body in the new state, the smooth running of the swivelling spout is preserved even if one of these rotation possibilities is obstructed.
