Jim:
That is a good suggestion.  I now remember it.  I used something similar 
for coax line as well.  No strain on the connexion.  The Lexan was also 
used for the centre insulator and was in a triagular shape, apex down.   It 
was clamped together with tye-wraps at the top and a carriage bolt (brass) 
at the bottom.
