An investigation conducted by Abt and Levy (1972) regarding the open cluster NGC 2516 indicated binary characteristics in the case of six stars. However, the observational material obtained was not sufficient for a computation of the orbital elements. A new study including the determination of the radial velocities of 14 objects in NGC 2516 was, therefore, undertaken. It was found that the stars Cox 29, 91, and d are spectroscopic binaries. This result confirms conclusions reported by Abt and Levy. With the aid of the new data it was possible to compute the orbital elements of the three systems for the first time. The binary nature of Cox 11 and Cox 20 suspected by Apt and Levy, appears, however, doubtful. The data obtained in the case of the stars Cox 15 and Cox 19 indicate possible long-term changes in the radial velocity.
