On GCVS, WDS and CCDM catalogues, a search for eclipsing variables in visual double and multiple stars was performed and the list of 421 eclipsing variables was obtained. Using the mass-luminosity relation for the main sequence stars, the masses of multiple components were estimated. It was shown that for about 85 % cases the masses of visual components are half as much as the masses of close binary systems. The distributions for the orbital elements of the visual binaries were constructed and used for calculation of the semi-major axes of our list stars. The observed distributions for semi-major axes and orbital periods were approximated by Gaussians with the maxima in a = 800 a.u. and P = 7600 yrs, respectively. The distribution for the semi-major axes more than 800 a.u. is better described by Opik's law. We suppose this law is true for less separation as well. The frequency of eclipsing binaries in the multiple stars is 12 % from the total number of the stars of that kind in the General Catalog of Variable Stars.
