How to securely connect cable to AXA Quattro dynamo? See the image: How do I securely attach the cable to the dynamo?



I tried the obvious, threaded the cable through one of the holes in the plastic cover, and pressed the cover snugly onto the socket. This was OK for some rides, but in the end the plastic cover fell off and the cable is loose.
I called the shop where the dynamo was bought, and let me explain
how to connect a cable. My summary:


Unplug the plastic cover from the correct socket: One is for ground,
one for phase.
Thread the dismantled tip through one of the two holes in the cover.
The length of the dismantled tip should be so that part of it
protrudes below.
Bend the protruding piece by 180°. The plastic cover is recessed to
accommodate the piece. See the photo below for the final result.
Press the plastic cover on the socket.


When posting the question, I had missed step three.
