Quick Release fittings

[Bented]

Hi,

I have a question about these quick release fittings...
I.e: http://www.specialtech.co.uk/spshop...or-12-ID---58-OD-13-16mm-Tubing-cid-3020.html

Is this the whole thing in one?
Or do I need to buy two parts?

If you would remove the "I.e" from that link, it would work

you need a male, and then also a female
