The first end portion is attachable to the nipple by having the nipple introduced into the first end portion. The strengthened portion includes a main segment adjoining the first end portion and having a wall thickness that is thicker than the wall thickness of the main hose portion. The strengthened portion also includes a transition segment adjoining the main hose portion and having an upper part ( 17 ) and an opposite lower part ( 18 ). The upper part has a wall thickness that is thicker than the wall thickness of main hose portion. The lower part has a wall thickness that is substantially equal to the wall thickness of the main hose portion. |
