Abstract: A preconditioned air adapter chute for attachment to a ring connector of an aircraft has a body adapted at a first end to attach a hose for transmitting the preconditioned air. The body is provided at a second end with a flange for connecting to the ring connector. A compressive gasket is affixed to a surface of the flange which faces the ring connector. At least one clamp assembly, affixed to the body, has a handle and a clamp pivotably mounted in a housing. The handle and clamp are pivoted about separate pivot points, so that a cam action is obtained as the handle is moved from an open to a closed position. The clamp of each clamp assembly passes through a slot-like opening in the flange to allow engagement of the clamp in the connector.
