What is this part called

[Limpy]

Hi everyone. I'm new to biking and have had my 2007 YBR for a couple of months now.
Today I had a go at doing my first bit of proper maintenance today. I removed rear wheel to check the rear brake pads. Unfortunately, what I would call a "butterfly pin" snapped and I'm going to need to replace it. Can someone please tell me what the proper name of the part is?

The pin can be seen in the video at 0:15.

Thanks for any help you can give.

You can alternatively employ a re-usable "R" pin.

R pin are much safer compared to other pins coz it has some groove into it that simply locks within the edge of a bolt.

A new split pin is deffo more secure than an R pin, the problem is when split pins get re-used, weaken and break. On the other hand, R Pins can get pinched.

I'm sure if Teflon was around he'd remind us that split pins should really only be used once?

wow.......no spelling mistakes ,

maybe Teflon 's gone minimalist?
