In this paper a condition, which is necessary and sufficient, is determined when a retraction of a subgroupHof a torsion-free groupGcan be extended to a retraction ofG. It is also shown that each retraction of a torsion-free abelian group can be uniquely extended to a retraction of its divisible closure.
