Dust cover assembly for quick disconnect coupling

A dust cover assembly for a relatively elongated, generally cylindrical open-ended conduit comprising:

• a clamping member for mounting said assembly encircling said conduit adjacent said open-end;
• a cover member equipped with an indention generally aligned with the axis of said conduit;
• pivot means cooperatively interconnecting said clamping member and said cover member, said pivot means including a pair of transversely spaced-apart ears on one member, said ears each having a longitudinally elongated pivot opening, and the other member having a pivot shaft outside said cylindrical conduit and extending transversely to the axis of said conduit, said pivot shaft being slidably pivotally mounted in said pivot openings so that the cover member is rotatable with respect to the clamping member about two mutually perpendicular axes and the cover member will align with and effectively close the open end of the conduit when the cover member is in a closed position relative to said open end;
• and a spring having one end engaging said clamping member and another end being received in said indention of said cover member urging said cover member into a closed position relative to said open end, said clamping member being equipped with a recess for accommodating said spring when said cover member is pivoted to an open position.
