Somewhat related to this question. (Open bottles shabbos)

In order to open champagne bottles one first has to untwist the metal tie.

champagne tied with metal twist

"Everybody" seems to open champagne on Shabbat - and the Shmirat Shabbat Kehilchato doesn't mention it in his chapter about opening various bottles and containers. (Chapter 9)

If twisting metal is a type of sewing, then untwisting it should be like ripping, also forbidden on Shabbat.

So, why is this permitted on Shabbat? (sources appreciated).

It is permitted to open and close then on Shabbos. Although there is controversy regarding twist ties, if they may be opened and closed on Shabbos. Most authorities hold that it is permitted, and although some people are stringent with this, the halacha is that essentially it is permitted.

Additionally, this case is even better than that, because here you are not fashioning anything, because the metal is already wound together. You are only tightening and loosening the already wound tie. Therefore everyone would agree in this case that it is permitted. Additionally, the bottom ring is similar to a lock that is evident that it is made to open and close constantly, and therefore permitted.
