The new chain cover

I have a six years old Abus security chain on the bike. It is an Abus Granite Extreme Plus. When I bought my bike, the CBF 600 in 2011, I have kind of overspent on security a bit. It was around £300 pounds, but it is a very secure lock. The only problem it had was that the cover was wearing out, so every time I took it off the bike, the chain touched the rim, causing some scratches. So i looked around and decided to buy a new chain cover. I bought one from Rydestore.com, for less than £2! (https://www.rydestore.com/ryde-heavy-duty-fabric-chain-cover-1-8m.html). On a Friday just after work I thought I would dress up the chain in its new cloth, it should not be longer than five minutes. I was so wrong! I needed around one hour for the whole process. I have noticed that the chain has a very thoughtful design, at the end of the last link, there is a plastic piece that closes the whole thing. I was struggling with it as I tried to put it through the new cover. However it turned out it is possible to take the plastic off and back on, as you can see on the following picture:

Eventually it is like I a new chain:
