Claim:
Connecting device for connecting discharge devices ( 2 ) to packages ( 3 ) with liquid products ( 4 ), preferably foodstuff products, for discharging said products ( 4 ) from the packages ( 3 ), wherein the packages ( 3 ) have walls ( 8 ) of synthetic material, wherein the connecting device ( 1 ) includes two connecting members ( 9 , 10 ) which can be connected to each other, namely a first connecting member ( 9 ) which is located on a wall ( 8 ) of the package ( 3 ) and a second connecting member ( 10 ) which can be connected to said first connecting member ( 9 ) for connecting the discharge device ( 2 ) to the package ( 3 ), wherein the first connecting member ( 9 ) has a hole ( 11 ) or a notch for a hole ( 11 ), said hole ( 11 ) being closed by means of a closing member ( 13 ), wherein the second connecting member ( 10 ) has a tubular member ( 14 ) by means of which the closing member ( 13 ) can be penetrated for opening the first connecting member ( 9 ), wherein the tubular member ( 14 ) can be inserted into the hole ( 11 ) and pressed onto edge portions ( 16 ) of the hole ( 11 ) such that the tubular member ( 14 ) adheres to said edge portions ( 16 ) and the connecting members ( 9 , 10 ) adhere close to each other, wherein the hole ( 11 ) in the first connecting member ( 9 ) has four, five or six corners ( 15 ) and edge portions ( 16 ) which extend between said corners ( 15 ), and wherein the tubular member ( 14 ) of the second connecting member ( 10 ) has a corresponding number of corners ( 17 ) and edge portions ( 18 ) extending therebetween, wherein the edge portions ( 16 and 18 respectively) of the hole ( 11 ) and the tubular member ( 14 ) respectively, are concave and arcuate relative to the centre (C 1 and C 2 respectively) of said hole ( 11 ) and said tubular member ( 14 ) respectively, and that the concave and arcuate edge portions ( 16 and 18 respectively) of the hole ( 11 ) and the tubular member ( 14 ) respectively, connect to each other for defining the corners ( 15 and 17 respectively) of said hole ( 11 ) and said tubular member ( 14 ) respectively.
