I've got SRAM hydraulic disk brakes with some sort of in-line connector.

I've managed to bollocks up the lower part (between brake and conector) while changing the fork, so I need to replace that bit of cable (rather than swap out the whole thing with the fun that would be), but for the life of me, I cannot work out what the correct name is (my google-fu is weak).

Can someone please tell me what the part I'm looking for is called?

One of these?

Usually, you need a barb (goes in the end of the hose), an olive (goes around the hose) and the compression nut to clamp the olive and hold it all together.

On the second one, the end is called the banjo - see description.

You can usually get the bits individually, or as a smaller pack without the hose.

Is it a mid hose connectamajig?

My bike has them and it seems to be pointless seems that you can split the hose without losing any fluid.

Yes, it's a mid-hose thingy.

Useful in this situation as the hose below goes through a channel in the fork, and I've knackered that bit.

it is called a brake hose in-line connector/coupler

Ok - it's called a SRAM Connectamajig

Which they don't sell separately.

Anyway - eBay is my friend and I should have it by the weekend.

Cheers.
