Abstract: The present invention relates to a ring belt. Locking units are provided in both ends of the ring belt so that they may be removably coupled to each other. An extension is formed to start from the end of the ring belt in which one locking unit is provided to extend along by the inside of the ring. A coupling ring is provided in the top end of the extension for holding a lead or a lifeline. Another coupling ring is also provided in the position corresponding to the coupling ring in the ring belt for holding a lead or a lifeline while both the locking units remain locked together. Such an arrangement enables both these coupling rings to be located in the adjacent positions with both locking units locked together so that the lead may be connected with both coupling rings. This will cause a force from the lead to be transmitted to the extension in such a way that there is no influence of this force on both locking units.
