I saw the thing at the MBS Strictly Sail Tent last week and it looked
like a simple tool to fabricate and expensive to buy ($50)

I tried some searchs on wire hose clamps and found tons of wire hose
clamps but kept playing with search criteria until I found their
website,
here it is :

check out the sites links

I would be less concerned about the wire cutting into the hose because
multiple wraps would spread the load, what would concern me more is
corrosion of the wire as the diameter is not all that signifigant.
maybe monel would be a better option ???
