There isn't a male part. It's a clip designed to clamp onto that black strap.
You pinch the top two prongs together and pull it towards you (it pivots from the bottom) and it'll open. The strap then slots behind that bit of plastic. Clip back to secure.
It's called an annex clip, it allows you to attach things to webbing/a MOLLE system and is (sort of) quick release compared to other attachment methods.
