1. A disposable flow set comprising:
- a) a drip chamber or a spike;
b) a first administration tube to administer liquid from said drip chamber or spike;
c) at least one pumping tube-segment, connected to the first administration tube, enabling said flow set to be installed in a liquid pump;
d) a second administration tube installed at an end of said at least one pumping tube-segment;
e) an anti free flow valve installed on the second administration tube;
f) at least one identifying key which is connected to the at least one pumping tube-segment has a respective identifying key connected thereto; and
g) at least one stretching key, whereby the at least one pumping tube-segment has a respective stretching key connected thereto;
wherein said stretching key is ring shaped in order to allow detection of air in said pumping tube-segment by an air detector through a hole in said stretching key.
