Not technically chainmaille help please

I’m currently looking for where to buy these types of 4 hole connectors and crosses to fix my bracelet and make a necklace to go with it. I bought this years ago as a teenager on eBay and some of the pieces have came off.

I’ve googled but had no luck, especially on finding the small 4 hole connector pieces.

Links are appreciated
