You then have two options –
You can either leave it like it is (in which case I would recommend a small dob of glue behind the solid end to hold it firm) - OR -
You can cover the exposed end. Slide the barrette/clip into the cover as far as it goes, (keeping the clip snapped open makes it a bit easier). Gently pull back the end,and grab the “hood” with your fingertips/nails. Gently pull this “hood” over the end.
