Call a colouring of a graph \emph{distinguishing} if the only automorphism of this graph which preserves said colouring is the identity. Let $H$ be an arbitrary graph. We say that a graph $G$ is \emph{$H$-free} if $G$ does not contain an induced subgraph isomorphic to $H$. Kargul, Musiał, Pal and Gorzkowska showed that if $n$ is a natural number greater than two, then every finite connected $K_{1,n}$-free graph of order at least six admits a distinguishing edge colouring with at most $n-1$ colours. We extend this result to all locally finite connected $K_{1,n}$-free graphs of order at least six.
