Abstract

L'invention concerne un dispositif de support (14) permettant d'assurer le support d'un tuyau souple sous pression (12), tel qu'un tuyau souple d'abrasion par projection, le dispositif de support (14) comprenant un support de montage (16) conçu pour être disposé sur le tuyau souple sous pression (12), le support de montage (16) délimitant un axe (22) de tuyau souple avec lequel une section du tuyau souple sous pression (12) est alignée lorsque le support de montage (16) est disposé sur le tuyau souple sous pression (12) ; et une poignée rotative (18) reliée de façon rotative au support de montage (16) pour une rotation sensiblement autour de l'axe (22) de tuyau souple. L'invention concerne également un système (10) comprenant un tuyau souple sous pression (12) et un dispositif de support (14).
