no nipple globes could be held by spring clips.
the home depot globe could be a slotted twist, like maybe a 10 degree turn and pull down, it would be 3 or 4 L grooves with one leg open to the top, a pin or dimple rides in the groove. it could release at anytime so keep a hand on it. make sure to give it a slight right (probably) twist before you take your hangs off it if you don’t get it down (you don’t want to have it unlock and decide to let loose later).
a very good suggestion is going to the store and see a new one.
