A tubular milk hose device of a teatcup liner forms an inner channel adapted for transporting milk to a claw having an inlet nipple. The hose device comprises a end portion (1) having a first outer surface (21), a strengthened portion (2) having an outer contour (22) with a varying radius and a main hose portion (3) having a third outer surface (23). The hose device also comprises an upper sector (10) and an opposite lower sector (11). The outer contour projects outwardly with respect to a longitudinal center axis (x) from the first outer surface and the third outer surface. The strengthened portion has a primary part (21) adjoining the end portion and a secondary part (2") adjoining the main hose portion. The radius of the second outer contour of the primary part at the upper sector is shorter than the radius of the secondary part at the upper sector. |
