Disclosed are a flexible plastic hose (1) and a method of manufacturing a flexible plastic hose (1). The disclosure notes that the flexible plastic hose (1) is able to resist higher bending and pulling force exerted between its end fittings (5a). The flexible plastic hose (1) comprises a hose body (2) and a cuff (3a, 3b). The hose body (2) has a flexible tubular outer wall comprising web portions alternating with reinforcing rib portions of at least one helical reinforcing rib. The web portions have predetermined properties, such as material or dimensions, for providing flexibility to the hose body (2). The at least one reinforcing rib has predetermined properties, such as thickness, material or pitch, for providing crush resistance to the hose body (2). The cuff (3a, 3b) is mounted to at least a first extremity of the hose body (2) and comprises a moulded end fitting (5a) having a bore. The end fitting (5a) is bonded to the first extremity of the hose body (2). The cuff (3a, 3b) further comprises a stress relief element (4a) having a first segment with an internal screw thread complementary to the helical reinforcing rib for closely fitting around the hose body (2).
