Buckle-style keychain accessory that allows you to quickly separate part of your keychain, while still being secure enough to not risk accidental separation during daily use. Useful for USB drives, security tokens, fingernail clippers, etc.

The Male end comes in two versions. The normal version (with more angled prongs) is nearly impossible to separate by pulling (very secure), while the _pullable one (with flatter prongs) can be separated by tugging firmly. I personally prefer the pull-able one because it makes separation really quick and easy, while still being plenty secure enough not to accidentally separate just from taking my keychain out of my pocket.
