A retention mechanism (1) in a dispenser for retaining an exchangeable roll of material, the retention mechanism (1) comprises a housing (2) including a front wall (21), wherein an insertion slot (4) for a bearing pin (80) of an end plug (5) of the exchangeable roll extends along the front wall (21). A cam lock (6) is arranged in the housing (2) so as to be rotatable in a plane which is parallel to the front wall (21) and to the direction of extension of the insertion slot (4). The cam lock (6) includes a retaining means (12) which is movable between an open position and a locked position by rotating the cam lock (6). When the retaining means (12) are in the open position, the bearing pin (80) can be inserted into the insertion slot (4), and when the retaining means (12) are in the closed position, the bearing pin (80) is retained in a locking section of the insertion slot (4).
