Abstract
A retention mechanism () for a dispenser for retaining an end plug () of an exchangeable roll of material includes an insertion slot extending between a receiving end () and a seating region () for inserting a bearing pin () of the end plug. The bearing pin has at least a first portion () with a first diameter, and a second portion () with a second diameter smaller than the first diameter. A pin discriminator () is at least at the receiving end and narrows the receiving end so only bearing pins can enter the receiving slot which have a maximum outer diameter in the second portion which equals the second diameter. A rejecting slot () extends from the seating region and is dimensioned so only bearing pins with a predetermined maximum diameter in the first portion which is smaller than the first diameter will enter the rejecting slot.
