Abstract
L'invention concerne un sifflet déviateur (10) récupérable de tubage continu et son procédé d'installation. Dans un mode de réalisation préféré, une pluralité de liaisons d'ancrage (14, 16) pivotent au niveau d'une extrémité et présentent des éléments de contact (46, 48) situés sur une extrémité arrondie opposée. Lesdites liaisons sont configurées pour donner une angle de contact optimal par rapport à l'axe longitudinal du sifflet déviateur dans une variété de tailles et de poids de boîtiers. Un système d'anneau de verrouillage sert à maintenir la position fixée, et l'extrémité supérieure est articulée et sollicitée afin de rester hors du passage du ou des éléments de fraisage, et d'être mise en contact facilement avec un outil de récupération.
