These are various modified Technic Bricks with "[Joint Ball Half](https://www.bricklink.com/v2/search.page?q=Joint%20Ball%20Half#T=A)" and "[Rotation Joint Socket](https://www.bricklink.com/v2/search.page?q=Rotation%20Joint%20Socket#T=A)" features as they are called on Bricklink. [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. Although there are more ways to attach them. 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):
