I *think* these are called brass compression sleeves here in North
America. They are called brass olives in England.
You can get them from most any plumbing supply store. They are about 25
cents each (or less). They are also much much much easier to use than a
bubble flare- slip them on and tighten it up.
I bought sizes from 3/16 to 5/16, smallest was used to patch my oil gauge
line, and other two were used on fuel lines.
My car also (had) olive fittings on the brake lines. Shame! They have
now been replaced with one solid line from master cyl. to tee.

Brake tubing is probably soft enough -- dimebank's right. It depends
on the brake tool. A bubble flare is radiused, different tools will
produce different radii.
Personally I bought pre-bubble-flared lines from one of the better local
car shops. They come in 'standard' lengths (44,54,60"). Then you can cut
them and use bubble on one end, and double on the other.
