Anti-debris device for covering connectors in fluid system

An anti-debris device for covering part of a fluid-conveying quick disconnect connector, comprising:

• a boot defining a closed cavity with an access opening, and including resilient fingers that flex to a cavity-closed position when unstressed, but that flex to a cavity-access-allowing position permitting entry of an unconnected end of a quick disconnect fluid connector into the cavity when the unconnected end is pressed against the fingers.

An anti-intrusion device for covering a fluid-conveying quick disconnect connector, the connector including a fluid-conveying passageway, comprising:

• a boot defining a cavity shaped to receive an unconnected end of the fluid-conveying quick disconnect connector, the boot defining a connector-receiving access opening, and a closure member normally covering the connector-receiving access opening but being flexibly movable to a connector-receiving position with minimal clearance around the unconnected end and the closure member so that, when engaged, foreign matter will not enter the cavity nor enter a covered portion of the connector.
