Everybody here has stayed on the adhesive train! I say use a mechanical
solution. Pin or swage it together!

Good thought, but:

If I did this I'd be using relatively thin wall tubing; pinning would
either rip out, or require me to use thicker tubing than I want.

Swaging would, I'm pretty sure, vibrate off as the tubing stretched.

Shrinking the tubing onto the end, followed by shrinking a collar on,
might work -- but that's extra weight, and I think I'd rather try glue.
