How to finish this kind of necklace???

[MBrinck]

Hello everyone,

I'm not sure if my question is okay here.... I have discovered a knotted necklace that has a knotted clasp through which a bead is then threaded. I like this type of clasp sooooo much because it's something different. Unfortunately, I have no idea how to work this clasp. Can anyone help me? Does anyone know a Youtube tutorial? Does anyone know the name of such a clasp? Best regards, Meike

This is called a lariat loop or lariat clasp. It looks like the loop was crocheted.
You can use the ring end of a toggle clasp for a loop instead.
