Is it the sort of tank with a tap on the bottom? I found these far to soft
to attach anything with no leaks. It ended up me using an old kitchen tp ap
fitted and then you can use normal hose fittings.

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.

Either a 3/4" or 1" tank connector, together with a hozelock type
connector

If you want a tap to turn off the hose, then this might suit better

Be aware you'll need access to the inside of the tank to screw on the
back-nut.
