Damixa Saturn mixer tap

[copthornemike]

One of the tap handles has gradually worked loose on this monobloc mixer tap and there is no obviously visible way of either removing or tightening the handle.

Has anyone tried to a) remove and b) tighten the handle?

There is no cover / screw which I can see on the handle so does the handle simply pull off (after turning off the water supply of course)?

Your advise would be greatly appreciated.

If it is like mine, you can pop the little disc with the hot cold indicator (red and blue dots on it) off using a sharp instrument in inside you will find an allen screw.... however you will probably find that the plastic sleeve that fits over the shaft which carries the handle is broken.. so just tightening won't help.
