Patent ID: 8167337

Claim:
A quick-release elastic coupling for deformably joining different diameter vacuum extensions comprising: an elastic sheet impervious to fluid transfer having a top surface, a bottom surface, a first end, a second end, a first edge and a second edge; said elastic sheet having a relaxed unstretched at rest size and shape that can be elongated into a stretched configuration; a first strip of hook-loop fasteners extending along and adjacent said first edge on said bottom surface; a second strip of hook-loop fasteners extending along and adjacent said second edge on said top surface; said first edge and said second edge being at least one inch long and long enough to extend over the ends of first and second respective adjoining conduits with at least ½ inch extending over the exposed extent of each conduit; said first end and said second end being at least two inches long and long enough to extend around the circumference of respective first and second adjoining conduits with at least a one inch overlap in the stretched configuration; said elastic sheet being stretchable to conform to the shape of vacuum extension conduits to secure and seal their ends together.
