Abstract
Disclosed is an anti-buckling device () which is made of an elastic material and comprises several ribs () that extend in the longitudinal direction thereof, the space between two ribs () forming a groove (). The anti-buckling device () is inserted into a thin-walled duct. The anti-buckling device () prevents the duct from buckling and thus from being occluded in a bend when said duct is bent. A fluid is able to circulate within the duct and bypass the bend in the grooves () of the anti-buckling device (). The envelope of the cross section of the anti-buckling device is essentially lenticular as a duct having a round cross section also becomes lenticular in a bend.
