Abstract: The invention relates to a connection between a tower (7) of a wind generator and its foundation established by an interface formed by flexible elements independent from one another which are formed by a series of tensioned cables (1). Each of these cables is located inside vertical housing means (4) which are embedded in the foundation. The invention also relates to a method of execution of the connection between a tower (7) of a wind generator and its foundation (8), comprising a series of stages, some of which vary depending on whether or not the foundation (8) has central lightweighting. It also generates variation in some aspect if the tower is made of metal or concrete and, in this case, if the tensioning cables of the tower are common to or independent of those of the connection.
