Option 1: The ITW QASM Buckle (female portion) is an extremely versatile piece of hardware. It is designed to lay flat and can easily be attached or removed from any 1" PALS webbing. This is particularly useful on load bearing gear and packs, to allow modularity. When paired with the the GTSR Ladderloc Latch (male portion), these buckles can be used for any number of non-permanent attachment solutions. These are sold as two pieces, male and female.
Option 2: The GTSR Split-Bar, is just as useful as the QASM and can be used to modify your gear in a non-permanent way. The female portion attaches to any 1" webbing loop, allowing the user the option to quickly clip in pouches or compression straps to packs and bags. We use these on our gear, specifically our chest rigs and we highly recommend them.
