Broken pipe clamps are easily replaced. Flat-bladed screwdriver is the only tool necessary for their removal. Any plumbing shop, auto parts store, or box store with a plumbing department is apt to inventory replacement clamps in a variety of sizes..
The broken clamp can be removed without disconnecting and removing the sewer hose. Like the original, the replacement clamp is openable. The worm gear drive to adjust clamping pressure also feeds an opened clamp end.. Simple and easy!
Actually, I would be surprised if your problem is solved by replacing the clamp. Usually, because of the long term period of eight years (2016-2024) on the hose joint, the rubber is probably bonded to the drain pipe. In my experience they are always seized. There might be more than the obvious casuing the leakl Check for other damage to the connection. Look for hairline cracks. They can produce impressive leaks when the system is pressurized by the pump.
