They use these type of things to win oil filters rotten a car. Otherwise you can use a leather belt in equal way. Just make sure you turn the correct process.

When it is off you replace the filter inside place the seal within place and tighten again. Make sure you turn the water off and release the pressure as it make it difficult to remove.
