I cooked a beautiful 3 day beef rib dinner and when my wife was breaking down the equipment the clamp broke. 
I have been an original supporter of Anova and as such my machine is the original … the big ol’ black top, the one button to start it, and the dial for setting the temperature.
The clamp they have is for Anova 3.0 so the obvious question is : will it fit my machine, and if not what WILL fit my machine???
My clamp broke a year or two ago, likely for being called a ‘clamp’ as I clamped it around the PC causing the thermal stresses. The new one was too big and that saved it. I linked four zip ties together around it at the lowest plastic surface, making four nubs that hang on the holder. Works fine so far, and don’t rust, bust or collect dust (it fails safe and drains to the bilge - basic requirements for a sailor approved device).
@DarcSceptor the Anova 3.0 clamp will absolutely not fit your machine, the 3.0 is much slimmer than the OG model. I’d certainly take a look at eBay to see if there’s one for sale, but maybe you can just fashion something using Home Depot parts if you’re handy.
Well, as you know Anova doesn’t seem to sell replacement clamps or parts. How about a strap wrench and bolt it to a C-clamp?
