<p>The saddle (1) has a valve section (2) and a looping section (3) that are separated between each other at the level of two junctions to open the saddle, where the saddle is rigid. One of the junctions is formed by continuous adjustment of gap between the sections by locking/unlocking a clamping screw (7) via orifices in respective tabs (10, 11). One of the orifices is elongated in a radial direction of the saddle, and one of the tabs has a cylindrical or spherical bearing. The screw is locked with a nut (9).</p> |
