I Can the Christoffel connection be observed?

Wald, p34: a Christoffel symbol is a tensor field associated ...

I looked at that section the last time you mentioned it, but I thought you were joking. Apparently you are serious. Then I can only recommend that you read the whole section, and see how it is written in the context it is written. If you don't read the whole section but just search for the key words, then it is no surprise that you are confused.

It does not mean that if one has read the whole section, that one will not be confused.

True, but you should at least try.
