I have just removed a roof light fitting which is wired two way (i.e. can be
switched on/off from two different switches) to find that the junction box
is a metal rod in three separate segments. One segment has two screw
terminals - the two wires are therefore electrically connected. The other
two segments have three screw terminals each.

It fell partly to bits but it looks like the three segments are meant to
line up and slot into the side of a clear plastic sleeve which keeps the
three segments apart.

I guess whoever fitted this "junction bar"(?) did so because it takes up
very little space.

I have tried to find something similar to replace it with but without much
success. Does anyone know where I might get one?

It doesn't have to be identical, but there is very little space so a full
size junction box is no good.

It sounds very much like the wiring in a conventional ceiling rose...
any chance it could be one of those, chopped down to fit?

How much space do you have? You can get quite tiny 'normal' junction
boxes like this, at 57mm diameter:

Or a choc box connector?
