A system includes knobs on an item of gear and a latch attached to a carrier. Each knob has a neck and a head with a larger diameter. First and second sliders fit into a latch frame. Hooks on the sliders form expandable apertures. To attach, the knob is pushed against the slider hooks to expand the aperture. After the head passes through the aperture, a spring biases the hooks together so the aperture width is smaller than the head diameter, capturing the knob. A carrier adapter adapts the latch to a carrier. Adapters are available for duty belts, MOLLE-equipped carriers, and horizontal slots.
