Sh”t Tzitz Eliezer 16:6 is lenient because it isn’t not even considered temporary. 39 Melachot (Rabbi Ribiat; pg 813) permits since the tabs are made to be used that way.

  9. ↑ Korban Netanel (Shabbat perek klal gadol 7:50) forbids using a safety pin on Shabbat by putting the safety pin through a cloth. However, the achronim including Sh”t Igrot Moshe 2:84, Shemirat Shabbat KeHilchata 15:70, and Kitzur Hilchot Shabbat (pg 67) permit because the pin doesn’t connect the two objects but rather keeps them close together like buttons.

However, Sh”t Shevet HaLevi 3:51 is strict unless one plans on unzipping in a short period of time. Rav Shechter (quoted by Rabbi Rosner between minutes 37:30 and 38:30) is strict for this opinion and doesn’t zipper his Shabbat talit bag because of this.

Halachically Speaking quotes Rav Yisrael Belsky who is also strict regarding zipping the inner lining of a winter coat because it is left there for a long period of time.
