The t-bolt clamp noted by TTF is commonly used for turbo hoses, and for marine exhaust hoses, which are often made of silicone. The band overlaps itself so as to provide uniform compression of soft hoses like silicone, which don't like being pinched.
A similar band, equipped with 3 or 4 v-section shoes on its inner face, is used to secure "v-band" joints, found on marine and aircraft exhaust plumbing.
Joining the t-bolt parts to the band is not something you would want to do in the field. You need very high quality spot welds, or complicated end prep of the bands. My crew has occasionally shortened Voss clamps by cutting and welding, but it's not for the faint of heart; it's the sort of thing you do at 3AM when the boat sails at 7AM, and order a proper replacement as soon as you can.
There is something even simpler, sort of. To use "Band-It" clamps, you unroll stainless or aluminum strap from a roll, lace it through a special 'buckle', fold the end over, then use a not terribly expensive special tool to grip the tail of the strap, pull it hard while bearing on the buckle, then cut off the excess strap and fold it over within the buckle, making a _permanent_ hose clamp of any size. They work something wonderful, but are not reusable after removal.
