Examining a table lamp I found the live conductor fractured &

Replacing a lampholder, flex & threaded tube insulator is easy.
Brass switched BC lamp holder w/red safety pin (will not turn on if a
bulb is not present).

Adding a cord grip is not easy.
This lamp (and many more) are custom glazed pottery, Troika style,
just a hole in the side.

I notice the brass lamp holder has an "strain relief bar" where you
loop back the insulated cores - like some ceiling rose fittings that
do not use a slotted-disc around the cable sheath.

Does that meet the requirement of a cord grip, so I do not need one in
the base?

Otherwise I will have to diamond drill the side and epoxy in one of
those plastic nylon cord grips with a plastic side grub-screw.http://www.ryness.co.uk/products/689...grip-9001.aspx

The only other alternative is a side-outlet cord-grip lampholder boss,
they are £9.

I'm not convinced I understand what you're describing.

I'm not sure what you're referring to as "threaded tube insulator" --
is that the nipple on to which the BC lampholder screws?

You refer to a "just a hole in the side" -- is that an existing flex
entry point in the base of the lamp but one that's simply too small to
admit any obvious mechanical cord grip, or what?

If the only problem is that there's no mechanical gripping of the flex
where it enters the base of the lamp, then use a bit of creativity.
An excellent use for silicon mastic!
