Abstract
Fittings are provided for flexible sewage drain hoses to connect recreational vehicles to sewage facilities as may be found in public parks or other locations. The fittings include a shallow groove for storing an elastic ring, and a wider, deeper groove for placing the flexible sewer hose thereover. The ring can be quickly, easily manually dislodged from the storage groove and directed over the end of the hose where it contracts and securely holds the hose onto the fitting within the wide groove.
