Fluid transfer channel`s flexible pipe end and rigid tube end connecting system for automobile field, has tooth presenting right section for opposing rotation between rigid tube and flexible pipe after being assembled with each other

摘要

The system has a nozzle (5) with retention teeth (7), which is machined towards the end of a rigid metallic tube (1) and on which an end of a flexible pipe is fitted with force. A tooth (7a) of the nozzle presents a non circular right section for opposing relative rotation between the tube and the pipe after being assembled with each other. The tooth has a right section in the shape of frustum of cone with an edge (10) at a hexagonal base.
