SW-Motech T-LOCK bracket

Assembly instructions here
The T-LOCK mounting bracket allows accessory pouches to be attached to MOLLE-equipped saddlebags and tank bags by means of a quarter-turn lock. The MOLLE system is present on all PRO Series tank and saddle bags, as well as on many Legend Gear Series bags.

This gives you greater luggage-carrying flexibility, allowing you to set up your panniers according to your needs.

The T-Lock is made up of two parts: the lower part of the T-Lock attaches to the pannier's MOLLE loop via a star-shaped adapter, and the upper part attaches to the pannier via a 90-degree pivot.
