A dispensing device (11) for dispensing one-component or multi-component masses contained in vessels has a piston rod (21) and a forward feed mechanism (31). The forward feed mechanism (31) has a first clamping lever (32) and a second clamping lever (42) each of which is arranged on the piston rod (21) so as to be axially displaceable and swivelable in longitudinal direction (L) of the dispensing device (11). At least two spring elements (33, 43) act upon the clamping levers (32, 42). The device (11) further includes forward feed means for actuating the first clamping lever (32) and the second clamping lever (42) and having a first forward-feed element (34) cooperating with the first clamping lever (32) and a second forward-feed element (34) cooperating with the second clamping lever (42).
