My laptop power supply came with a standard UK to clover leaf lead plus an additional UK13A plug direct to the cloverleaf allowing the power supply to be mounted direct.
I could do with some more of them for other PSUs but cannot locate any, and so far cannot find a picture online either. Does any know of any suppliers?
Is it a cloverleaf to 13A cable you want, or a 13A/cloverleaf integrated plug?
The cloverleaf connector is called C5 (the appliance inlet is C6):

so a search for "C5 cable" will turn it up for you.
But a combined 13A (Type G) plug with fixed C5 connector is going to be harder to find. In any case, the exact position of the C5 connector may affect whether your PSU will fit on it or not. I suspect it would have been custom-made for the PSU.
