It is known that the period of the eclipsing binary V505 Sgr changes, and that the changes can be explained - at least partly - by a light-time effect. The system is also known as a speckle binary. In this paper parameters of the third body orbit are suggested in order to explain both sets of data. Some discrepancies in the size of the orbit and radial velocity data remain. Next periastron passage should be at 1998.9.
Key words: binaries: eclipsing - binaries: visual - stars: individual: V505 Sgr
