What are these fittings for polytunnel called and where do I find them?

[MisterBoy]

Watching this handy video:

THere are a few fittings he uses which I cannot find anywhere. All I get are regular U-bolts:

I cannot find that rounded "arched pressing" to grip the tube onto the U-bolt, or a corner bracket of that style. He mentions "U clamps" I can't find either.

Even this simple u-bracket thing that wraps around a pole I can't find:

One aspect of the modern world is I don't have a hardware shop I can go in and describe what I need, so frustrating not to be able to name the thing I want especially when they're pretty common Neither Screwfix nor Google is turning up what I'm after.

Anyone able to help?

Exhaust clamp, scaffold clamps if it's 48/50mm tube, kee klamp.
Some parts will be custom made.
For the U shaped strap in the last pic, just bend a bit of steel, or galvanised banding.

Contact polytunell suppliers, they will have some of these items, depends what diameter your tubing is.

There are shops that sell some of this stuff, industrial suppliers and bolt/fixing suppliers on industrial estates, but you're not likely to get them in the big chain retail shops

Maybe that's it. I was sure I've seen them before - maybe I'll ask my local steelwork place who do tube-clamp stuff.
