Conex compression - you need about 1cm max play - do you not have even that much flex?
Otherwise chop a section out and use a solder slip coupling to insert a new bit of pipe to join into the tee (can be slid onto one pipe fully, then slid back over the other pipe).
Chop a lump out and use plastic or a flexible connector or even a bendy corrugated copper section.
