I have to connect this AAA battery holder to a toy. Although I have a
small soldering iron, my soldering skills are poor. I can see myself
easily melting all the plastic around the contacts before I can get
anything to stick to the tabs. (The part of the tabs with the small hole
will bend upwards giving some clearence).

My immediate plan is to poke a few strands of wire through the holes in
the connection tabs twist and then apply some nail varnish to stop it
unwinding. Since its a toy it does not need to be totally foolproof.
If anyone had any ideas that were a bit more sophisticated I would be
gratefull. Thanks.
Solder is the only reliable way, IMO
Just bend the tabs out, so they are not touching the plastic, make sure the
iron is nice and hot, dab some solder on the end of the iron, then place
this on one of the tabs and feed in a little more solder to tin the tab,
should take a couple of seconds.
Now strip about 5mm of the wires and tin the end of the wire, if the
insulation shrinks back, then snip the end of the wire off so it is about
5mm.
Place the wire on top of the solder on the tab and heat the wire until the
solder on the tab melts again.
Hold the wire with something other than your hand, as it may get quite hot!
Once it has cooled, marvel at your handywork :-)
Or, buy these two from eBay, or anywhere that sells this sort of stuff...

Ore use a conductive "glue" like the stuff sold to fix rear window
defroster grids, or printed circuit traces. After making the good
electrical contact with that (it is usually silver bearing) add a dab
of epoxy, or even hot melt glue, to give it a bit of mechanical
support.
Or just learn to solder - - - - .the low temperature eutectic "paste
solder" would actually work pretty good for this and only requires
minimal heat.
