Tightening RCA Interconnect ends

Have an old pair of Pandora S Interconnects with RCA ends that are loose. Is there a good way to tighten these up that?
funny I just posted about how I sent my Pandora S in for fixing and Tara did it for free including shipping.

I paid for shipping there but a gift overall IMO.
Do you mean that the sleeves are loose when slipped over the RCA jacks on the amp/preamp? This has happened to me with expensive interconnects, but my solution is the same as with cheap ones: a needle-nose pliers and gently increasing inward pressure on pairs of opposing tabs. Anyone else do this?
