Abstract
A hose (24) constitutes a part of a milking machine and has an end portion (30) which is radially expanded and applied on a tubular nipple (29), the outer diameter of which exceeds the inner diameter of the hose. The milking machine includes structure for providing a negative pressure in the hose. The hose is reinforced by including at least one elongated reinforcement member (25), (26) which consists of material substantially harder than the wall of the hose and which extends along the hose in a helical cavity in the wall of the hose. In addition, the reinforcement member completely fills up the cavity and is arranged therein, such that relative movement between the reinforcement member and the wall of the hose is allowed.
