The invention refers to a teatcup liner, a teatcup and a milking unit as a milking machine member. The teatcup liner (I) is mountable in a teatcup shell (2), having a first end (3) and a second end (4), in such a manner that it in the mounted state extends through the teatcup shell (2) and forms an inner space (5) to a teat and an outer space (6) between the teatcup shell and the teatcup liner. The teatcup liner (1) includes an opening for introducing a teat into the inner space. The opening is located at the first end. The teatcup liner also includes a grip area (10), which is arranged to be gripped by a grip portion (11) of the teatcup shell in such a way that the grip area is surrounded by and abuts the grip portion. The grip area (10) has, seen in a cross section, a non-circular shape. The teatcup liner (1) has a connection portion (20) for being connected to a teatcup claw (9). The connection portion includes means (22) arranged to define a rotary position for the teatcup liner (1) in relation to the teatcup claw (9).
