yEd is an editor for graphs (see Wikipedia for a formal definition) and in a graph there can be no edge-to-edge connections. The "restriction" to graphs is essential for many of yEd's features (most notably its layout algorithms).

The common workaround is to split the edges you want to connect using size 1 nodes and then connect these split nodes.

Please see Connect Line to line for detailed instructions.
