If you don't like it, I'll trade you short clip for it....
As for removing it....take off the o-ring, try to fit a very small flat tip screwdriver under the clip and push the black plastic retaining wedge out, next pull clip out with needle-nose pliers....toward the threads of course.
Put the head end down onto workbench while using screwdriver to push out wedge. Be careful not to slip and hurt yourself. It can be tight sometimes.
Hope that helps
