Polymer duct having clamping collar

摘要

A polymer duct configured to be connected to a nozzle of a system for transporting a fluid has a circumferential groove into which is mounted a clamping collar configured to clamp the duct against the nozzle, the groove being delimited by two lateral rims comprising radially projecting lateral studs with which the collar cooperates to be rotationally blocked relative to the duct. The collar has a circumferential clamping strip having two ends which overlap in an overlap region of the strip, a strip clamping member and a non-metallic blocking cover having an abutment portion. The abutment portion has a pair of lateral fins which extend in the radial and axial directions and abut against axial and lateral faces of the lateral studs.
