ABSTRACT:
Apparatus for preventing fluid flow upon decoupling of first and second fluid delivery tubes, wherein the first fluid delivery tube includes a reception outlet and the second fluid delivery tube includes an insertion outlet for insertion and coupling within the reception outlet, the reception outlet including a pair of arms pivotable outwardly from the reception outlet for decoupling the outlets and pivotable inwardly for coupling the outlets, one of the fluid delivery tubes including a valve for opening and closing the one tube to fluid flow, the apparatus comprising a pair of ears mounted to the one tube including the valve, the valve including a handle pivotable between valve open and valve closed positions, the ears being pivotably mounted to the one tube including the valve for pivotable movement between a position interfering with pivoting of the arms and a position of noninterference with pivoting of the arms, the ears being connected to the handle of the valve such that when the ears are pivoted to the position of interference the valve is simultaneously pivoted to the open position and when the ears is pivoted to the noninterference position the handle is simultaneously pivoted to the closed position.
