I've never had my hands on a Samco clamp but I believe all you need or maybe all they are is a "lined worm clamp" that you can find in most medium/heavy duty truck suppliers.
I've used these on the silicone hoses on trucks, taxi/police package cars etc.
Fleet-Pride is a nationwide supplier that I'm quite sure stocks Breeze and there should be a Fleet-Pride near you!
They will also have the t-bolt style and maybe a prevailing torque style but the important "feature" you're looking for is "lined"! If they have any with a "floating bridge" look at those also.

I'll "eye-ball" a couple of cars tomorrow at Carlisle to see how similar they are but I'd guess if yu got an early start you could be "hosed and clamped" by the time I could pass on the information!!
