The replacement chains use the permanent link.
The tool has very little resemblance to one for a bike chain. The bike chain tool is a link breaker. The MB tool holds the plate in place while pressing the prettiest crimp you ever saw into the link pins. If the link was out where you could see the beautiful crimp, it would make the tool worthwhile, but since it's hidden in the engine where no one can see the difference, skilled use of a ball peen hammer will provide the same final result.
Have a great day,
