Expanding pe-x Barrier pipe

[mickmath]

After installing an extra radiator using barrier pipe for the first time, I noticed that the pipes when hot expand, (I understand why they have) I have not put any clips in yet, but when I do is the expansion likely to pop one of the fittings, with pipe being secured.

Barrier pipe is used very frequently these days....so long as you used an insert, and nipped the fitting up firmly all will be well.
