I think your best opporuntity might be with Directive Systems 
(www.directivesystems.com) or M-squared (www.m2inc.com).  Both of these 
companies use the retainers you describe on the VHF/UHF yagis they sell.

I don't think you'll find these parts in a common hardware store.  
Perhaps in some sort of specialised hardware store, but I'd try the 
links above first.
