Abstract: Let *M* be a manifold modelled on a metrizable, locally-convex, topological vector space *F* such that , and let *K* be a closed subset of *M*. Then the following are equivalent: (1) *K* is locally a subset of a collared submanifold of *M*, (2) each has an open neighborhood *U* and a homeomorphism such that , (3) each has an open neighborhood *U* and a homeomorphism such that , (4) there is a homeomorphism such that for , (5) *K* is infinite-deficient (i.e. there is a homeomorphism such that , and (6) *K* is the finite union of sets each having one of the above properties.
