Abstract: The invention relates to a device for fixing scraper strips to a printing roller scraper. The inventive device comprises at least one magnetic element (3) which is configured and disposed such as to hold a first face of a longitudinal support portion (1a) of at least one scraper strip (1) in firm contact with a support surface of a body (2) of said scraper (10), a second free longitudinal portion (1b) of said scraper strip (1) occupying a projecting position. Alternatively, the magnetic element (3) is also configured and disposed such as to maintain a hold-down plate (5) in firm contact with a second face of the support portion (1a) of the scraper strip (1), whereby said second face is located opposite the aforementioned first face which is in contact with the body (2). In this way, the support portion (1a) of the scraper strip (1) is trapped between the hold-down plate (5) and the support surface of the body (2).
