Hose conector for this

i have no idea what i am doing does anyone know what hose connector to get for this please?

 

Hi. Never had to solve that problem but does the tap have a thread on the end?? If so one of these should work.

Just may be wise to wait till someone answers the question as I am sure this has been overcome

 

I don't know how good they are but there are a few here on this link.
