What's the name of the buckle/clasp pn bike helmets and backpacks?

Question

Im talking about the ones with three prong things and when you insert it into the other side the outer prongs slip through two holes on the outside.. and to open it you squeeze them back inside...

Answer 1

they're called buckles. the end with 3 prongs is the male end, the other end is the female end.

this answer was pretty disappointing, sorry.

Answer 2
