[Technic Rotation Joint Ball Loop with Two Perpendicular Pins with Friction](https://www.bricklink.com/v2/catalog/catalogitem.page?P=47455#T=C) are the connectors for this type of elements.

These elements have been used in large number of sets, originally coming in brick-built figures like [Danju (8770)](https://www.bricklink.com/v2/catalog/catalogitem.page?S=8770-1#T=P):
