Abstract
A telescoping crossbar assembly for a wheelchair comprises an inner tube that is slidable within an outer tube. The head portion of a pass-through fastener bears on the inner tube through a sufficiently large head-side aperture so as to slightly deform the inner tube and to hold the two tubes by friction in mutual engagement.
