Summary:  The paper is devoted to closed modular densely defined operators on a Hilbert $C^*$-module $W$ over the $C^*$-algebra of compact operators on a Hilbert space. A bijective operation preserving correspondence of the set of all such operators and the set of all closed densely defined operators on a Hilbert space is obtained. The polar decomposition of a closed operator is generalized as well as some results concerning operators with compact resolvent, relative compact operators and the generalized inverse.
