Where can I buy a clamp that would do this

I have a thick horizontal cylinder. I want to clamp a thinner vertical cylinder so it's sitting on top of it. This must be a very strong attachment that could handle a lot of weight and wouldn't slip off, but it must also be easily removed. Any ideas? Thanks!

Also, are these tubes parallel? or perpendicular?

What do you consider "a lot of weight?"

The chain clamp idea is good for 1000s of pounds of weight. Lengths of chain secured by bolts would probably be good for 100s of pounds. Hose clamps for 10s of pounds.

drilling +pinning can't hurt. Clamping a cylinder can have a way of getting wonky.

There are what is called chain clamps: http://www.irwin.com/tools/locking-tools/the-original-locking-chain-clamp
You can buy extension chain if you need more length.
I modified a few of my locking pliers to use bicycle chain.

What size cylinders are you talking about? Anyway, a big enough C-clamp or woodworkers bar/pipe clamp should work. On the bottom end of the clamp, you need to cut a support block with a V groove in it. It will center the pipe so that the clamp has a flat surface to bear on. The throat length of the clamp will determine if you can fit it over and if it is big enough for the height of the vertical cylinder and bottom cylinder diameter. I guess there is some cap or solid end of the vertical cylinder to clamp on. Of course, this does not prevent it from rotating the whole thing if you decide to pull on it hard enough.

There may be some specialy clamps, but if its going to take weight, I'd consider drilling them and putting pins with split ring or just lashing. My concern about clamps I'm familiar with is that they are not really designed to be secure things that move. I.e. they are great at pressing things together quickly, but if those things move and flex (b/c they are under load) the clamps can and do spring apart. ...and if one clamp goes, odds are most of the rest will.

Lashing doesn't take very long and is a very strong way to connect cylinders. You'd probaby have to cut and retie when they shift but it would be secure. Look for diagonal lashing like the one they do here. http://camp.wonderhowto.com/how-to/use-diagonal-lashings-tie-poles-together-387300/

Heavy duty band clamps might work if used in a lashing pattern, but please test extensively how well it works and hold with shifting loads. Something like http://www.rockler.com/product.cfm?page=27100&site=ROCKLER

If you can, go with pins or old fashioned lashing. It's a tried and true method for a reason. My $.02 anyway.
