EDIT: Forgot to mention: I'm talking about collaborators in Antwerpen of course, it would be weird if they were thought from all over Europe to be displayed in a Zoo.

Yes. The Imperial War Museum has a load of pictures of this very incident.
This was a notable but by no means unique event. Collaborators across Europe were punished by a variety of means, typically ─ but not always ─ in accordance with the severity of their crimes. Women had their heads shaved, their clothes torn and were smeared with excrement or graffiti. Some were executed.
The punishment doled out to men tended to be more physical. Beatings and stonings (with bricks and cobbles) were common. I believe ─ but don't have statistics immediately at hand ─ that men were more likely to be executed. Men and women alike were driven from home and family, or at the very least were shunned.
Children didn't escape, either. In Norway, there is the case of the Lebensborn, the children born under a Nazi program to arrange births between "Aryan" women and German soldiers. After the war, these children and their mothers were shunned and kept under special surveillance by the Norwegian government, which until the 1960s monitored them closely for Nazi-like behavior including (literally) goose-stepping and inclinations toward fascism.
