Easiest way to fit these is to remove the repeater from the car, making sure the wire and connector don't fall back through the hole!
Get some good quality clear silicone sealant and smear around the black plastic rim of the repeater. Twist the metal ring onto the repeater and smear the silicone across the joint between repeater and ring. This won't be seen once the repeater is refitted. This should keep the ring in place. The repeater can be removed by pushing the unit towards the rear of the car which compresses the clip. Reinstall action is simply the reverse. Did these in about ten minutes. I'll update if they fall off!
