Replacement swivel back clip to attach any item from my store with a Standard 10x3 male clip front.
Push replacement STD 10x3 female clip back in through the opening on the back of a belt clip with the smaller part of disk going in first.
Snap STD 10x3 male clip front into the clip back.
Use needle nosed pliers to squeeze the male clips from the back if you need to remove an accessory from the belt clip. Warning...this may destroy the male clip.
