Connecting module, maintenance device and maintenance method for maintaining a closed-circuit breathing apparatus The present invention concerns a connecting module (10) for installation into a breathing circuit of a closed-circuit breathing apparatus (1000) comprising an inlet connection (12) to which a first circuit element of the closed-circuit breathing apparatus (1000) is connectable, an outlet connection (14) to which a second circuit element of the closed-circuit breathing apparatus (1000) is connectable, at least one fluid inlet (16) through which maintenance fluid can be introduced into the breathing circuit of the closed-circuit breathing apparatus (1000), and at least one fluid outlet (18) through which maintenance fluid can be discharged from the breathing circuit of the closed-circuit breathing apparatus (1000). The present invention concerns, moreover, a maintenance device for closed-circuit breathing apparatuses (1000) comprising the connecting module (10) as well as a controller (30) and valves (40), controllable and/or adjustable via the controller, in which, when the connecting module (10) is installed into the closed-circuit breathing apparatus (1000), maintenance fluid and/or gas can be circulated through the breathing circuit by way of the controller and the valves controlled by the controller(40). Moreover, the invention concerns a method for maintaining a closed-circuit breathing apparatus (1000), comprising the following steps: Opening the closed-circuit breathing apparatus (1000) in at least one location, installing a connecting module (10) or a maintenance device (1), and introducing the maintenance fluid into the breathing circuit of the closed-circuit breathing apparatus (1000) through the connecting module (10) or the maintenance device.
