Here we introduce some new results which are relative to the concept of topological monoid-groupoid and prove that the category of topological monoid coverings of X is equivalent to the category covering groupoids of the monoid-groupoid π1(X). Also, it is shown that the monoid structure of monoid-groupoid lifts to a universal covering groupoid.
