Abstract: Panel fasteners or tether clips are disclosed that include a first retaining means near a first end that is adapted to be securable to a first panel, a second retaining means that is engageable with the second panel and limits the relative separation between the panels, and a releasable fastener means intermediate the first and second retaining means that normally maintains the two panels in a closed configuration relative to one another but that releases at least one of the panels relative to the other panel in response to a predetermined force tending to separate the panels.
