Quick lock coupling is mechanically similar to snap-on coupling, but featuring an additional self-locking component. Disengagement of connectors requires locking to be disengaged by retracting the unlocking-sleeve located on the male connector. This mechanism provides all advantages of snap-on coupling while preventing unintentional loosening.

Connector series featuring this mechanism include: QMA, QN, and some precision connector variants such as Type-F 1.0/2.3 and Type-F 1.6/5.6.
