ABSTRACT:
Disclosed is an anti-buckling device (1) which is made of an elastic material and comprises several ribs (2) that extend in the longitudinal direction thereof, the space between two ribs (2) forming a groove (3). The anti-buckling device (1) is inserted into a thin-walled duct. The anti-buckling device (1) 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 (3) of the anti-buckling device (1). 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.
