I have an electric blanket where the insulation has escaped from its clamp.
Totally easy fix, as long as you can get into the fitting. But there are no screws or anything. There are three recessed holes that look like some kind of melted plastic rivet or mushroom.
How can I open this fitting to re-place the power cable without damaging it ?
My plan is to drill it out a bit at a time. When closing it I would drill a small short pilot hole and use a short self-tapping screw into the plastic, and then fill the recess with something to prevent skin/metal contact. Does that seem sufficient?
