Abstract: An unreeling hook for string for training a climbing plant, said unreeling hook comprising a hook (C) designed to be hooked onto a support cable and an unreeling reel designed to receive a hank of string, said unreeling hook being characterized in that said hook and said unreeling reel are arranged in such a manner that, by hooking said hook onto said cable, said cable expels said hank of string from said unreeling reel.

Abstract: The invention relates to a device for unwinding a flexible support wire for vines, comprising a dispenser having a rack (12) provided with means for fastening to a carrier cable, a winding reel (14) for said support wire, mounted on the rack (12) rotatably about an axis of rotation, and rotational retention means for the winding reel (14), which are capable of assuming a retention state in which the rotation of the winding reel (14) is blocked and a release state in which the winding reel (14) is able to rotate freely. The device includes remote control means for guiding the changeover of the retaining means from the retention state to the release state and conversely.

Abstract: A device for securing and holding a plant creeping along a support wire (11), comprising a fastener (12) configured as a skewed-surface, open ring composed of an annular web (21), which delimits an internal volume (13) for receiving the plant through an access opening (16), and a pair of hooks (14, 15), which are bent back outwardly at the ends of said web to form semi-open retaining eyes (17) that are offset in the heightwise direction and make it possible to exert a wedging effect on the support wire due to oblique deformation relative to the vertical direction. The fastener (12) is hingeless and is made in one piece from biodegradable material.

Abstract: A device for training creeping plants by means of a substantially vertical, flexible support wire comprises a reel with quick attach means to effect attachment to a carrying cable. A winding spool for the support wire is mounted so that it is able to rotate. The reel comprises: an immobilizing lever (33) mounted pivotably about a pivot axis between a position of clamping the support wire and a position of releasing it, the support wire being disposed, in the clamping position, between a first jaw (39), which is integral to the immobilizing lever (33), and a fixed second jaw (27) opposite the first jaw (39); and automatic return means (36) that return the immobilizing lever (33) toward the clamping position.
