Abstract
A mobile milking unit has a pipe rigidly secured to a first connection means coacting with a second connection means at the inlet of a valve through which the unit can be releasably connected to a vacuum line, a valve body in the valve housing normally closing the passage between the valve inlet and the vacuum line. When the two connection means are coupled together, the valve body is automatically moved to open said passage and thus create in the valve housing a vacuum which serves to hold the two connection means together with a pierced truncated cone of the second connection means closely fitted into a socket of the first connection means, one of said connection means being elastic to facilitate its release from the other connection means.
