ABSTRACT:
A rubber teat holder for milking cups having a suction sleeve section which conically enlarges adjacent its upper edge and transforms into an enlarged holding edge for gripping over the milking cup housing. A ring lip extends radially inwardly from the holding edge toward the longitudinal axis of the suction sleeve, the inside diameter of the ring lip being smaller than the inside diameter of the conically tapering part of the suction sleeve. An annular gap is provided between the ring lip and the upper end of the suction sleeve and the annular gap is dimensioned so that the part of the ring lip which extends between the holding edge and the mouth of the suction sleeve forms a lever arm which can be loaded by alternating pressure differences between atmospheric pressure and suction pressure to render the lever arm pivotal with respect to the holding edge.
