A tube set for use with a surgical pump and tool system to supply irrigation fluid to the system is provided. The tube set includes a cassette for insertion into the surgical pump to engage a peristaltic pump of the system that is concealed within the surgical pump. The cassette includes a front, first and second spaced apart opposed sides that extend from the front, and a rear opposite the front that extends between the sides. The cassette includes a locking finger having a retention feature for engaging a retention feature integral with the surgical pump. The locking finger is movably attached to the first side to move towards the second side so that, when the locking finger is so moved, the locking finger retention feature disengages from the surgical pump retention feature.
