Could someone enlighten a non technical person about what fittings i can get, that will
enable a plastic garden water tank to be drained by connecting it (securely and
non-leaking) to a 20 metre length of standard (1/2") garden hose please.

The simplest way would be to siphon it. Assuming the bottom is off the
ground anyway. And the relative levels in the garden.

Get a short piece of hose with connectors all ready to attach it to the
20 metre hose. Fill the short piece of hose with water, one person holding
it the other filling it from a can.When it runs out the bottom put your
finger there and keep it tight. (which is why its harder to do
this from a tap with the pressure)

Put the other end in the tank but near the top to start with. And position
the end with your finger over it lower down on the outside. Water will
run out of the tank down the hose which you can then connect to the longer hose.

The end of the longer hose would however need to be lower than
the end in the tank at all times. But that could possibly be got round by filling
an intermediate container.
