Flexible fixation made of concrete blocks that have at one of side surfaces bosses in hemispherical form and at opposite surface - depressions for hinged connection of one block to another and through mounting openings provided in center of its side surface. To simplify mounting and to increase reliability depressions are in elongated form in horizontal with rounded edges. To mounting through openings polyvinylchloride pipes are tightly installed, through those mounting wire goes.
