Carabiner
With carabiners you can easily fasten and connect: You can attach loops, rings, eyelets, hooks or other snap hooks through the snap opening. Then the closed karabiner reliably protects against unintentional loosening of the connection. In addition to the conventional mini carabiners, S-carabiners can also be found. These are so-called double carabiners with two openings, each on one side. Thus, the opposite side is always secured against unintentional release when the carabiner is opened.
