1. Clamps installed on water hoses during factory assembly are disposable. After tightening the clamps, their free ends are clamped with a loop.
2. In order to remove such a clamp, you should either unclench the loop with a screwdriver or cut it with side cutters.
3. Even if you removed the clamp without cutting the loops, during assembly it should be replaced with a conventional clamp tightened with a screw.
