By a \bf generalized arc\/ we mean a continuum with exactly two non-separating points; an \bf arc is a metrizable generalized arc. It is well known that any two arcs are homeomorphic (to the real closed unit interval); we show that any two generalized arcs are co-elementarily equivalent, and that co-elementary images of generalized arcs are generalized arcs. We also show that if f:X → Y is a function between compact Hausdorff spaces and if X is an arc, then f is a co-elementary map if and only if Y is an arc and f is a monotone continuous surjection.
