Using a small flat-head screwdriver
Disconnecting quick-connect electrical fittings can be done in a number of ways, but one of the most common tools to use is a small flat-head screwdriver. This is a useful method when there is no obvious release mechanism. Before starting, it is important to wear the necessary PPE, such as safety glasses, gloves, and non-conductive footwear, to protect yourself from electrical hazards. Ensure you have shut off the power to the circuit you will be working on at the main breaker to prevent the risk of electrical shock.
If there is no obvious release mechanism, you can try to gently prise the connector open with the screwdriver. Be aware that different connectors may have different methods of release, so take your time to understand how it comes apart. You may need to use a small amount of heat from a heat gun to help release the connector.
For some connectors, you may need to push in towards the fitting on both sides to release the wire. This can be done with a small flat-head screwdriver by gently pushing in the connector and then releasing the pressure by pressing the release tab. Once the connector is unlocked, the wire should slide out easily.
It is worth noting that some connectors are not designed to be reusable, so using a small flat-head screwdriver may damage the connector. However, this method can be effective for removing wires from push-in connectors and quick-connect fittings.

Applying a blast of air and a squirt of penetrating oil
When disconnecting these fittings, it is important to take safety precautions. If the hose is pressurized, it is recommended to depressurize it first to prevent injury from the escaping air. This can be done by grasping the male and female ends of the connector, pressing in on the male end, sliding the lock sleeve on the female end, and allowing the male end to come out slowly. It is also important to look away from the hose or wear safety glasses to protect the eyes.
Once the safety precautions are in place, a blast of air can be used to clean the connector and a small amount of penetrating oil can be applied to help release the connector. This method can be especially useful when the connector is difficult to disconnect due to built-up crud or corrosion.
Additionally, there are tools available specifically for disconnecting quick-connect fittings. For example, a small plastic "fork" tool can be used to remove the connector by pushing the two loose parts on the end towards the fitting, allowing the copper to slide out. Alternatively, a crescent wrench can be closed around the pipe and pushed towards the fitting while removing it.
By following these steps and using a combination of air, oil, and specialized tools, one can effectively and safely disconnect quick-connect electrical fittings.
