Any ordered field can be considered connected if one simply uses the trivial topology.

Actually, both connectedness and the Heine-Borel theorem (that all closed and bounded sets are compact) can be shown to be equivalent to mono-tone convergence, least upper bound property, and Cauchy criterion. That is, given any one, you can prove the others. (Again, assuming the Eucliden metric: d(x,y)= |x- y|.)
