Jewellery making - What sort of connector/bail is this?

[JLCooper]

I'm making a replica of this necklace:

But I can't find out what the name of the type of connector/bail I would need to connect the horn to the chain is so that I can search and buy it online. If anyone knows or can direct me to a site that sells them it would be great :)

Thanks in advance.
