If you want the look and feel of aeronautical style quick-release connectors, this YC-8 4-pin Connector Matching Pair is an elegant and inexpensive alternative. Sure, they're not mil-spec but they do work and look great for DIY projects, keyboard builds, robotics, wearables and more. The connector snaps together smoothly, and can disconnect only when the sleeve is pulled, which can be done one-handed with a little practice.
