What is the secret to getting this plastic collar to snap or lock in place?
I can feel grooves inside the upper collar that seem to line up with tabs on the lower collar but they won’t lock together. Should they snap or twist lock or..?
I’m ready to try long screws dipped in pvc glue while a voodoo priestess circles the truck saying a chant.
