High quality "locking" IEC connectors?


Does anyone know of a high quality IEC connector (pure copper conductors w/plating) that actually locks into place? Something similar to the connection for a balanced interconnect? or maybe something like a twist lock connection? I'm sick of trying to prop up my power cords to ensure that they are connected securely. I've seen some lower quality connectors available but nothing with good quality copper conductors. This seems like such an obvious need in high end audio. Anybody have any ideas?

IeGO makes an IEC receptacle that has a support. You can find it on the CryoParts list. I haven't listen to the the IeGO connectors, but they've been building a good reputation and they're base is either pure silver or Furukawa copper.
Wow, very cool. Thanks for that lead Quackfat. I'll check that out right away.

Those Iego are very very nice! I've never seen that brand before. Thank you so much for that info. Do they lock together though? I couldn't tell and they did not mention anything to that effect. I'll shoot them an email and find out. Thanks again for taking the time to respond. This is an excellent lead.

Kenobi, Those seem to be for specific molded IEC ends. Most of the heavy audiophile power cords (the ones that do not want to stay in place) have large, round ends.
