USB connector, 3.5mm (1/8") stereo connector plug and socket lock

The original purpose of this design was as a 3.5mm connection lock for USB Compatible Programming FTDI Cable but can be used for stereo cables also. The 3.5mm (1/8") stereo connector lock clips on to the connection between male and female connections to prevent disconnection. The 3.5mm jack/plug this was designed for is used as a programming cable to hand held radios and scanners. This can also be used as a strain relief / connection lock for 3.5mm headphone extensions for home or automotive.
