Fluid couplings

A fluid coupling used in a hydraulic brake line of a vehicle for coupling a brake hose to a metal tube, wherein the brake hose includes a deformable inner layer, a braided wire layer over the inner layer and an outer layer of deformable resilient material over the braided wire layer, the fluid coupling comprising:

• an eyelet having first and second portions;
• the first portion having a stepped bore adapted to receive the metal tube and the second portion having a projecting nipple adapted to be received in the hose, the eyelet further having an annular exterior groove therein;
• a crimping cup having first and second ends, the crimping cup being disposed around the projecting nipple and initially having an inside diameter greater than the outside diameter of the hose, the crimping cup further having an inwardly projecting lip aligned with the exterior groove in the eyelet and a bell-shaped pocket adapted to be disposed adjacent to an end portion of the hose which has been stripped of the outer layer, and
• a coaxial strain relief element disposed in the bell-shaped pocket and being urged against the wire reenforcement when the crimping cup is deformed radially inwardly to press the inner layer of the hose against the nipple and the inwardly projecting lip into the exterior groove in the eyelet.
