Abstract
The invention concerns a manual scraping device (10) by rotation about the external surface of a tube (112) of plastics material, comprising an annular structure (11) having a passage (20) which is to receive the tube in order to guide it and a blade (30) secured to the annular structure (11). The passage extends right through the annular structure and is partially obstructed by a shoulder (50) defining a region (52) for restricting the passage, so that the shoulder defines an abutment for a non-scraped portion of the tube and permits the passage of a scraped portion of the tube through the restriction.
