I'm making up some flat IDC cables which terminate in a 0.1 inch pitch IDC header socket. This fits onto a board connector with 9 pins (one omitted).
Clearly I'd like to fill the unused hole to make it impossible to plug the things in the wrong way round. I'm probably going to use a blob of epoxy, but does anyone have their own easy way of doing it?
is a proper Polarizing Pin or Key available for the series of connector you're using?
Not on that list. These are the 0.1" pitch headers used on things sich as disk IDE cables; the holes are tiny. I haven't been able to source any, and they'd probably cost a fortune.

Bit of wire of the correct diameter for a tight fit, snip off. Job done.

A long time ago I bought some plastic pegs that you could inset for this purpose. They were V-shaped to hold into the hole and had a flat very thin top to cover the hole.
Might well have been RS or Farnell.
Good idea!
I tried Farnell but I'll look at RS. They do at least exist, then.
Yep, definitely seen them.
Next best thing is to dip a the end of a cocktail stick in epoxy and push it in firmly, cutting off the excess with flush cutters for a professional finish :-)
Not too much glue in case it migrates.
That's a good uk-d-i-y one!
We used to key our cable so you had to put them the right way around. However as I only ever ordered the ready made cable I've no idea where you get the bit of plastic. Thinking about it I've never see one loose - so I can only tell you the head was square, and had a mark in the top as if it had been broken from a bit of sprue.

That's the ones. Just ordered somew from RS. I note that some of them actually come with a handle and you break them off yourself after insertion.
Took a long time to find them though!
What's wrong with a single tooth from a fine hair comb? Far easier - shove it in, cut off with craft knife. Her indoors won't notice a single tooth missing!!!!

What do they call them?

I have quite a few to do...
Those particular ones - "Keying Plugs".
It's just knowing the keyword. That phrase shows 56 products on RS's website!

I tried about a dozen phrases on there before I happened on a similar product and thus found the phrase...
