A tamper-proof and ligation-resistant apparatus for dispensing a liquid from a liquid container contained within a dispenser. The apparatus includes a back housing, a cover pivotally coupled to the back housing, a liquid cartridge coupled to the back housing, and an actuator coupled to the cover. The apparatus includes plates coupled to the cover and back housing to strength the apparatus or reduce gaps to prevent ligation. The actuator includes a dispensing hole small enough to prevent ligation. A pump nozzle insert compressibly fitted inside the pump nozzle reduces the liquid stream diameter and extends the pump nozzle so that the liquid stream passes through the dispensing hole unimpeded.
