the bit between the twist grip and the cable

[Big Nick]

does anybody know where i can buy another one of these on it's own? After 30 years i don't know it proper name! A stall holder at the last Rye autojumble had them at 50p each , they come in 2 sizes and like a fool i bought the wrong size ( the smaller ) I need the larger.
Thanks

Ferrule.
Lightning spares, Draganfly, usual suspects!

I seem to remember back in the day it was called a throttle cable stop Chris

I know them as ferrules too.
Its worth wrappin a slivver of insulating tape round them, to prevent them falling off the cable and getting lost whilst you're working on the bike, be it in ther shed or on the roadside.
Cheers,
