Daughter called me to look at immersion heater. The neutral connection had failed. I trimmed back the cable and re-made the connections - but I felt a bit un-easy as the terminals seemed quite poor - a post with a nut for N and a small screw clamp in the thermostat for the +.
Are newer ones any better?
I am wondering if there is a better flexible that the one installed. Any recommendations?
That's normal as far as I have seen.
I suppose that you could (properly) crimp or solder a ring to the end of the cable and put a serrated washer above and below. The screwed terminal for the positive should be fine as long as it is fully tightened.
Mine seems to have some kind of ptfe sleaving over the wires near the actual connections, but I have to say the ends on the thermostat look and feel like ordinary piece to me but no damage has ever occurred, so I guess its ok. Brian
There's usually two washers on the post, so that the wire is clamped rather than screwed up. Otherwise what you describe is typical.
flexible what?

The 'elegant' way to connect is surely to crimp a ring terminal to the wire.
cable.
Indeed. Though many come with a dished washer with a cutaway, and at least that generates a more secure connection than just a loop clamped between two flat washers.
