<p>The retractor has associating unit (9) for associating the retractor with a vine post (1). A branch (5) is extended from the unit (9) and presents a free end (6) having a reception unit (8) for receiving a tying wire (3). The unit (9) is engaged around the post in a free manner in translation along the post under the effect of gravity or descending constraints exerted by the wire on the branch to tilt with respect to the post. The unit (9) support against the post for immobilizing the retractor in translation along the post.</p> |
