The present invention relates to a connecting device for use. If snow or ice accumulates on only one span of a transmission line support tower, or if snow or ice accumulates on both spans and then the snow or ice on one span derails the transmission line, Unbalanced tension occurred in the power lines, causing them to be pulled to one side, resulting in power lines being disconnected and steel towers toppling. In addition, even when the tension on the transmission line increased significantly due to snow or ice accretion on both spans, the transmission line could break and the tower could even collapse.
