L'invention fournit un élément de touret qui tout en allongeant un film adhésif, empêche un blocage ou une protubérance du fait d'une concentration de pression d'enroulement, et permet de prévenir un décalage d'enroulement, ou similaire. L'élément de touret de l'invention est équipé : d'un noyau d'enroulement (3) ; d'un corps élastique (4) de forme annulaire qui est mis en prise avec la face périphérique externe du noyau d'enroulement (3), et sur lequel est enroulé le film adhésif (2) en forme de bande ; et de rebords de touret (5) agencés des deux côtés du noyau d'enroulement (3). Le corps élastique (4) présente une dureté Shore A supérieure à 30° et inférieure à 90°.
