• a second end wall opposite of said first end wall and sealingly engaged with the flexible sleeve and forming a fluid chamber;
• an opening formed in said first end wall providing fluid access into the fluid chamber;
• a push-pull connector mounted in the said first end wall opening for receiving a tube therein for supplying fluid into the fluid chamber, said connector including:
• a) a main body member formed of metal and molded to said first end wall within said opening having an internal bore and a tube receiving space;
• b) a collet member rotatably mounted within the main body and having a plurality of flexible fingers communicating with the tube receiving space;
