A connector apparatus comprising a hose having a resilient core with a resilient cover over the core. A passageway is defined in the center of the resilient core. At one end of the hose the core has a region of reduced thickness that produces an increased inside diameter in the passageway at the end of the hose. A connector is engageably positioned in the passageway in the hose at the end where the core has a reduced thickness. The connector has an enlarged diameter portion and the enlarged diameter portion has a diameter larger than the inside diameter of the passageway in the hose. Clamping means is positioned on the exterior of the hose at the end where the connector is positioned in the passageway of the hose. The clamping means sealingly secures the connector in the hose.
