A liquid soap dispensing system includes a molded plastic housing adapted to receive a disposable refill cartridge containing liquid soap. Rails on the housing engage in recesses on the cartridge to guide vertical movement of the cartridge to its mounted use position, in which position it is latched by a latch member pivotally carried by the housing and engageable with the outlet neck of the cartridge. The neck carries a compressible discharge nipple engageable by a pump member actuated by a handle for discharging soap. Bias means holds the latch means in its latched condition and the pump member and handle in their normal rest positions. The dispenser includes a minimal number of parts which can be assembled without the use of fasteners. A key is provided for releasing the latch member to permit removal of a spent cartridge.
