Tightening Clip-On Earrings

Hello! I have Clip-On Earrings that became too loose. Does anyone know how to fix this problem? I have attached a photo of the earring, so you may see the Clip-On clasp. I appreciate any help! 20191206_222023.jpg

i only wear clip earrings (and mostly only really huge ones at that) and have a "key" (that's what the tool is called) to tighten them, and sometimes just use needle-nose pliers* but i'm not familiar with that type of clip back.

*don't do any work to your own jewelry if you aren't willing to mangle or destroy it. there are some pieces i'd never work on myself, and others that i could recreate if i broke them.

if they're sterling silver you might could take them to your local jeweler to see if they could tighten them up a bit for you.
