Reusable coupling for connecting the ends of a reinforced hose

摘要

A peripheral locking ferrule (4) is radially compressed and fixed to the periphery of a tube (1) by a connection assembly comprising an outer sleeve (9) and a clamping ring (10) mounted around the end of the tube on either side of the locking ferrule. The outer sleeve is positioned around a nipple (2) and comprises on its rear face an annulus capable of bearing against one end of ferrule. An internal cage forming a nut if provided on the front face of the outer sleeve. The clamping ring is positioned around the pipe in downstream with respect to the locking ferrule. The clamping comprises an external threaded portion that can be screwed into the threaded portion of the outer sleeve and an internal chamber capable of bearing against the peripheral surface of the ferrule, thereby crushing the ferrule and enclosing wall of the tube, as well as pushing the inward annulus (5) of the ferrule into a peripheral groove on the surface of the nipple and enclosing a seal between the annulus and the bottom of the peripheral groove.
