A drive means on the elongate portion mounts a U-shaped drive rod for axial movement. Each flange includes a slot for receiving a pin formed on a replaceable generally cylindrical cartridge to act as a bayonet fitting. Viscous material is expelled from the held cartridge by driving the rod axially. A nozzle attachment has a primary section connected to the exit of the cartridge and includes a secondary section for holding a replaceable hardener tube, with the hardener being expelled by axial movement of a portion of the rod. The nozzle attachment includes a planar end surface for simple cleaning.
