This is a small part for fitting a plug with a flat base to the slot of a My-Steel belt. Attach the connector to the plug with a material-appropriate adhesive.
For my application, I used a stainless steel connector with a steel plug and attached with JB-Weld. I'm also offering the connector in a couple colors of plastic for the cost-conscious. However, I haven't personally tried the plastic connector with a plug on a belt. Please let me know how this works out for you if this is the route you take.
