Shall I coat it with tar or PVA or woodglue

the sap will repair it from inside?

The last time I mended a split stem I used brown parcel tape. When I
moved house years later it was still stuck on and the stem had grown.

Yes, I've done something very similar and it does work. However, it
won't work if the rose stem is still bent or twisted so that the injured
area of stem is still agape. The two layers of stem must be bound
snugly together, as for a graft, so that they heal together.

I've just been out by torch light and applied 3 woodwork clamps, will
try to tie it tighter tomorrow.

Watering and feeding it might help - shall i buy special rose feed?

What you haven't said and no one has asked is
How thick is the stem?
Must be quite large if you can clamp it.
