Should the classes always have connectivity in UML? For example, in the following diagram, class Zugriff is not connected to any other classes. It that a valid or correct class diagram in UML?

Yes. You SHOULD but not MUST.
Class diagram is UML structure diagram which shows the structure of the designed system at the level of classes and interfaces, shows their features, constraints, and relationships - associations, generalizations, dependencies, etc. (from https://www.uml-diagrams.org/class-diagrams-overview.html)
These classes and interfaces should have a type of relationship so that it makes sense to put them together. A typical relationship is a generic (weak) use.

1Yours is not wrong. You have decided that based on whether your audience needs to know about that relationship. Think about who is reading the diagram. – Devs love ZenUML Mar 20 '21 at 22:16

1I would add it **if** those classes really "use" it. – Devs love ZenUML Mar 20 '21 at 22:27
