We prove an analogue of this theorem for linear forms of two independent random variables taking values in an <bold><italic>α</italic></bold>-adic solenoid containing no elements of order 2. Coefficients of the linear forms are topological automorphisms of the <bold><italic>α</italic></bold>-adic solenoid.</p></abstract><trans-abstract xml:lang="ru"><p>Согласно теореме Хейде гауссовское распределение на вещественной прямой характеризуется симметрией условного распределения одной линейной формы от независимых случайных величин при фиксированной второй.
