You can make the holes a bit oversize.  It's not like you're worried 
about the tolerances getting sloppy in 10 years of wind induced movement.

Actually, what might be easiest is this: glue a thin ring on the smaller 
of the two pieces so that it butts up against the larger piece when it's 
inserted to the right length. Slide it in with a snug fit some turns of 
tape, and you're done.

Why put *any* fastener in.  It only has to survive for a couple days, 
and duct tape will do that just fine.

You don't need hose clamps, screws, rivets, etc.

Your pre-FD prep would be cleaning up the elements a bit before 
assembly, throwing away that icky roll of tape from last year that's 
oozed over everything, and buying a new roll a tape.

the tent pole shock cord technique would work real well with this scheme 
too.
