I am suffering from what appears to one or more loose elements in my 2" ASA
corrector. Some in this group have had success correcting this problem by
tightening the retaining ring on the element closest to the secondary mirror.
Does anyone know if the lens cell has more than one of these retaining rings? In
other words, will tightening the exposed ring (end near secondary) apply
pressure to the remaining elements in the lens cell? I would expect this not to
be the case.

The one at the end of the corrector is the only retaining ring.
Taking it out you can dismantle the whole thing, and yes, tightening
it will apply pressure to all the elements in the lens cell.
