If your clutch "breaks" then the warranty company 99.9% otf the time will not pay as it is a wear and tear item, simples.
Any way, why do you want a warranty on your clutch as you bought a clutch and fly combo from me recently which comes with a no quibble warranty.
Most of the aftermarket insurance warranties are extremely hard work to succeed in getting a claim fully accepted.
If it is a wear and tear item then you have a snowball's chance in hell of getting them to pay out.
If it is failure or breakage due to manufacturing defect or similar then you will have a better chance of a successful claim, however the majority of failures are down to wear and tear.
