Abstract: Device for tying vines or other plants that can be trained by tying, using adhesive tape.A flat body (10), the rear portion (11) of which encloses a roll (2) of adhesive tape (20), its front part (12) housing a star-shaped wheel (3) with several spokes (30), mounted in free rotation around a transverse axis (31), with the end (32) of each of the spokes (30) being rounded and of a width that is approximately equal to the width of the adhesive tape (20). Said spokes (30) are surrounded by the side walls (34) separated by spaces (35,), with part of said star-shaped wheel (3) exceeding the length of its spokes on the lower edge (13) of the body (10), and being partially covered by a cog (4) in the arc of a circle, mounted in a pivot around an axis (40) to the front part (12) of the body (10) and held by a spring (41) against the ends (32) of the spokes (30) between the side walls (34).
