Abstract: An adapter for connecting a corrugated hose, e.g., a washing machine drain hose, to a standpipe has an elongated tube with a bell at one end for holding and retaining the corrugated hose. A curved support extends from the bell end of the tube and selectively supports the hose in a desired curve of from 0.degree. to 180.degree.. A sliding annular retainer ring slides on the curved support and selectively locks the corrugated hose in the chosen position. Outwardly extending ears on the end of the curved support hold the retainer ring on the adapter. The tube has longitudinal ribs over at least a portion of its length. The ribs provide additional strength and tapered portions on the ribs prevent the tube from jamming in a standpipe and provide for easy release. The ribs have enough friction to retain the tube in the standpipe in cooperation with the weight of the assembly and the water therein to prevent the hose from being forced from the standpipe by the jet effect of water moving therethrough.
