I tried with the

block, but it did not work.

Since the drop-down list of the touching block does not contain the own name of the sprite, I constructed the touching block in another sprite and dragged it over to the sprite with clones. However, the block always reports true.

Anybody has an idea how I can detect if a sprite is touching one of its clones?

If I were you, I would make a list which stores the X and Y positions, ID, etc. of the clone.
You can check each item of the list and see if the X and Y positions of the clone overlap with the X and Y of the main sprite. If it is, it is touching it and if it is not it's not.

Just have each clone see if its touching the sprite. Or does that not work? I don't remember.

<touching [main sprite v]> doesn't work.

It shouldn't be possible because the clone is the sprite, just a duplicate of it. So it is always touching itself.

Simple workaround: Duplicate the original sprite and have it follow that sprite around on top of it. You WILL be able to detect touching that sprite.

Hi!
I think it depends a lot on what you want to do… but:
I tried for a while to detect clone collisions when the sprites were moving freely (not after player input), but then I gave up, and looked for another way.

Instead of clones, I used lists of X-positions and Y-positions, as PhysicsWhizz suggested. Every cycle there is just one (hidden) sprite, without clones, moving around at each recorded position and making a stamp. In this way it looks like it's a lot of sprites moving.

If you want you can have a look at my project “More Bouncing Balls” here.

Hope this helps.
