Abstract: Let X be a compact connected metric space and denote the hyperspace of closed subsets (subcontinua) of X. Let . If is connected im kleinen at M, then is locally arcwise connected at M. A characterization of connectedness im kleinen in is given. Indecomposability of X is related to an absence of local connectedness in and . An example is given of a continuum X and a subcontinuum M such that is connected im kleinen at M but not locally connected at M.
