three to two socket adaptor for two pin plug [non-electric]

[alggomas]

I am not looking for a socket adaptor.
I'm looking for a thin plastic item with one prong which when slotted into a three pin socket changes it to a two pin socket.
This is for electrical appliances which are 240v BUT supplied with a two pin plug.
Instead of using a screw driver to force open the socket holes this fits neatly in place. I have no idea what it is called or how to search for it.
This is handy also for rice cookers and electric drills etc.

I have one from Malaysia but its past its days!!

a kiddy proof plastic socket blank cover plate with L/N pins cut off works upside down for testing but not good idea to use 2 pin plug in 13A socket for anything more than a very light load as unlike adaptors the pins will only just touch on each side of socket and can lead to arcing damage to plug/socket ,ALSO MORE IMPORTANT< you have no fuse protection in line only 32A at consumer unit so don't consider it please (the adaptors are fused), regards SPARX

Thanks for reply.
I use mine to charge my Drill battery and for my rice cooker.I have been doing this for years with no problems.These are also meant to fit 240v sockets as they are specially made. I all assume that these rice cooker etc are earthed anyway. [Though I will stand corrected!]
