How to extend cable for dew heater?

[Martin-Devon]

My dew heater cables are rather short, probably only 4 feet long and this is always a worry as my scope slews. Many times these cables become very tight and I have to readjust them so I want to extend them now if possible. I've attached a photo of the end of the dew heater cable, and the socket in the HiTec Astro control box into which they plug. Does anybody know if it's possible to buy an extender that will be compatible with these ends and which could provide another few feet?

Thanks,

Martin

They are probably "phono" connectors, that's the usual connector for dew equipment so you want something like this:

Thanks for the very quick reply Themos - I'll order a pair of these right away!
