Let $(ℝ,||·||_𝔹)$ be a Minkowski space with a unit ball 𝔹 and let $ϱ_H^{𝔹}$ be the Hausdorff metric induced by $||·||_{𝔹}$ in the hyperspace 𝒦 of convex bodies (nonempty, compact, convex subsets of ℝ). R. Schneider [RSP] characterized pairs of elements of 𝒦 which can be joined by unique metric segments with respect to $ϱ_H^{Bⁿ}$ for the Euclidean unit ball Bⁿ. We extend Schneider's theorem to the hyperspace $(𝒦²,ϱ_H^{𝔹})$ over any two-dimensional Minkowski space.
