This is a bad repair. Especially if the hose is part of the cooling system. The clamps that come stock in the car, are not ridged. Meaning when the fluid heats up the hose is also gonna heat up and expand. The clamps are made to expand along with the hose. The way your doing it. Wont be long ti that hose has a cut right along where you just clamped it. Sometimes what looks like a good idea , ain’t!
These come factory on fluid lines from German and European manufacturers, it’s just another option to have in the tool box. I’ve used these for a number of years with no issues small and large engines.
