The inner ring of the cable conductor has broken off and is stuck on the gold pin of Healy’s cable connection socket.

Note the LOT number (this can be found on the paper sleeve on the cable) and contact Customer Support to arrange for the cable to be replaced.

The broken piece should be carefully removed from the socket with tweezers; these should have teeth or grooves so that the gripping jaws interlock, ensuring safe grip when removing the broken piece.
