Is there an established German word for “contiguous” in the sense of contiguous simplicial maps?

Background

Definition. Two simplicial maps $f$ and $g$ from $\mathcal K$ to $\mathcal L$ are called contiguous, if whenever $S$ is the set of vertices of a simplex of $\mathcal K$ the set $f[S]\cup g[S]$ is the set of vertices of a simplex of $\mathcal L$.

I am teaching a class in German, and I will go with „benachbart“, if no-one knows a better word. I would look if the concept is used in Seifert and Threlfall, but I do not have it at hand.
