The author shows that the almost periodic solutions of a class of non-autonomous delay differential equations, with continuous delay, are quasi-periodic. This result is an extension of Cartwright's result related to ordinary differential equations (see [\textit{M. L. Cartwright}, Proc. Lond. Math. Soc. (3) 17, 355--380; Corrigenda. Ibid. 768 (1967; Zbl 0155.41901)]).
