TQD (T-Shaped Quick-Disconnect) Connector Kit - Female
This kit is delivered unassembled and without wire.
Included:

• 1 x TQD-F-Housing
• 2 x TQD-F-Connector

Not Included:

• Wires
• Mating connector

These are the same connectors found in many gliders as they are delivered from the factory.  They are used as battery connectors.  They have a positive "click" when connected and are easy to disconnect by hand without the need for any special tools.  I sell the components - unassembled and without wire. 

Wiring Standard?

Below is a description of how at least one Germany glider factory uses this connector.  You may want to follow the standard.

• The connector in the top (cross part) of the "T" was used for the common (black wire).
• The connector in the base (vertical part) of the "T" was used for +12V power (red wire).

Assembly Instructions

• Crimp and solder metal tabs onto the wire.  The metal tabs on the end of the connector are to be crimped onto the wire insulation. See assembly diagram below.
  
• Insert the connector into the back of the housing until it clicks into place.
