I understand that it's unlikely...but, it still makes me nervous and is bad practice. A hard plastic snap grommet is only a few cents and is one more layer of protection.
Thanks for the wright-up!

Yeah, I thought about it too. I looked around for a "grommet" but I found nothing in the right size so I choose to live without it at this moment.
I can live with the "risk" for now due to the overall configuration of the installation. Thick wire coating, no pulling force on the wire, "not that thin" metal cover, filed metal and the most important thing; fusing. Like you said, it's unlikely to happen in a short-term so...
But it's a a good general advice, thanks to you to point it out since I forgot to talk about it, and I'll continue seeking for one.
I also thought of using 2 coats of shrink tube over the wire coating where it passes through the metal cover if I can't find the right kind of grommet. I don't know if it will be enough but it's better than nothing and will makes me feel more comfortable if I need to. I'm using the kind of "glued" shrink tube that looks stronger to me than the "normal" stuff though.
