The clamp contains a first gear rack at one end of the clamp, and reverse second gear rack at the another end of the clamp, and guide creating with the second gear rack a fissured passage for the first gear rack. The radial poles are arranged along axis of the internal pipe and are provided with support shoes at the ends. One edge of the guide, one edge of the first gear rack, and one edge of the second gear rack are equipped with plate fixing shoulders. In the assembled turnbuckle the shoulder of the first gear rack is located between the shoulders of the guide and second gear rack.EFFECT: invention increases stability of the centring support due to increased reliability of the lock-on connection.3 cl, 3 dwg |
