If I think about it from a construction/assembly viewpoint there must be a way its installed in first place, without saddle in hand I can’t do more than conjecture… it just looks like assembly should be straightforward.The rail will not be weakened but the only way I can see of getting it back into that rear rear locating point is to cut that location hole open and then using something like araldite to fix the part cut off back on. Providing whatever glue you use holds it should be OK but I would subject it to some rigourous testing before riding with it.
Your only alternative is to see if you can get a refund from either the shop you bought it from or Ergon themselves. Maybe try that route first!!
