A modular slider feeder tube system comprising first and second feeder tubes having respective ends that are coupled by a tube coupling device. Each of the first and second feeder tubes is made of resilient material and comprises a respective channel having a profile that is asymmetric and substantially constant along the lengths of the channels. The tube coupling device also comprises a channel, via which channel the channel of the first feeder tube communicates with the channel of the second feeder tube. Each of the channels maintains the orientation of each slider passing therethrough so that the same end of the slider is always in the lead.
