See some others attached. Maybe not perfect to understand. There are 4 screw holes as various places on each tip.
I only used one, which kept it hidden as the screw thread is way longer than required.
My plan is to either get some much shorter screws of the same thread, or just use the one and some lock tight.
I've also included some pics of the old ones and what they look like when removed. They use a sort of spring and barb method. Literally biting into the underlying pipe.
