Abstract
Abstract A multiple passage tube connector fitting is provided which includes a pair of connectors each having a passage open at one end. The fitting has a single-piece elastomeric tube adapter and plug device having a coupling element for connecting it to the connector. The device includes a tube adapter having a passage through it which is connected by a flexible strap to the coupling element and is adapted to fit in the passage of the connector. Another plug is connected by a strap to theadapter for closing the adapter passage. The device also has a plug connected to the coupling element by flexible strap for closing the passage of the other connector.
