What holds the PVC in place?  Any glue or solvent?

I saw this at the Barks contest.  Really looked neat
Nothing. No glue or anything. The PVC must be sqeezed to slip it into the 
tube. Once in the tube it tries to expand back to its natural size and stays in 
place. 

I learned this trick from Gerry Dale before carbon fiber tubes were the norm. 
Works equaly well on aluminum tubes. 

Have even made fast repairs to striped out aluminum tubes at contest by 
cutting off a small piece of PVC tubing from a model stand and using it. 

This is one of the ultimate K.I.S.S. ideas I have seen. It is simple, easy 
and economical (cheap). It holds the wing screw like a locknut and spreads the 
forces over a larger area of the tube than just around the screw hole. It is 
light and easily repairable if need be.
