The invention concerns a manual scraping device (10) by rotation around the outer surface of a plastic tube (112), comprising an annular structure (11) provided with a passage (20) for receiving the tube and guiding it and a blade (30) attached to the annular structure (11). The passage runs through the annular structure on either side and is partly obstructed by a shoulder (50) defining a zone restricting (52) the passage, such that the shoulder defines a stop element for an unscraped part of the tube and allows through a scraped part of the tube through said restriction.
Dispositif (10) manuel de grattage par rotation autour de la surface externe d'un tube (112) en matière plastique, comprenant une structure annulaire (11) présen-tant un passage (20) destiné à recevoir le tube pour le gui-der et une lame (30) fixée à la structure annulaire (11). Le passage traverse la structure annulaire de part en part et est partiellement obstrué par un épaulement (50) définis-sant une zone de restriction (52) du passage, de sorte que l'épaulement définisse une butée pour une partie non grat-tée du tube et autorise le passage d'une partie grattée du tube à travers ladite restriction.
