Help with my Iss 4000

[Snippys]

I haven't been able to use to Intova ISS4000 strobe because the fiber optic cable wont stay in the strobe. Cant figure out why so i emailed Intova and they told me just to rubber band it in place but still couldn't get it to work. So i took it to my LDS and asked there they said i am missing something can someone please tell me what it is. The piece around where the cable attaches to the strobe.

Lots of wiggle room in the connection to the flash, but definite "click" to get the cable in or out.
