OK, this is killing me, so where better a place to come than GFY - I've asked loads of people here in France, shown them the picture and they all know what it is and what it's for, but do they know wtf it's called or where to buy one.... nope.
So, I'm turning to GFY -
this stupid piece of plastic you put in desks to allow cables to pass - wtf is it called in French? In English, I still have no idea, but a Round Desk Grommet is the best I found on a website to describe it.
Here it is:
If you can tell me it's French equivalent, then I can at least search for a place that sells them, cos at the moment, I've been in every DIY shop in town and everyone knows what they are, but noone can tell me where to buy them.
I am -><- this close to ripping a couple of the stupid things out of the desks in the shops because they are impossible to find on their own here! It's not like I need a factory load - 3 brown and 1 white are all I need!!
