Abstract
A hydraulic duct for feeding fluid at high pressure includes a rigid tube and a flexible hose connected to the rigid tube by a connecting assembly. The connecting assembly includes an endform in communication with the rigid tube over which the flexible hose extends. The endform includes a primary annular projection extending outwardly from a periphery of the endform and at least one auxiliary annular projection extending outwardly from the periphery of the endform. The primary annular projection includes a leading edge, a trailing edge, a landing region that extends axially from the trailing edge toward the leading edge and a stop bead that extends outwardly from the leading edge beyond the landing region.
