A docking assembly for a self-contained breathing apparatus comprises a seat, a coupler, a pawl, and a spring. The self-contained breathing apparatus generally includes a compressed air tank having a head and a nozzle, the compressed air tank being adapted to deliver breathable air to a user. The seat of the docking assembly is adapted to releasably retain the head of the compressed air tank. The coupler comprises a plurality of circumferentially spaced teeth and a handle and is adapted for threaded engagement with the nozzle of the compressed air tank. The pawl is mounted to the seat for pivotal displacement and adapted to engage at least one of the plurality of teeth on the threaded coupler to lock the threaded coupler onto the nozzle. The spring biases the arm into the locked position.
