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?

I feel your pain. As far as gripping power goes, I have found Furutech connectors the best that are out there. Sonically, some will say the Oyaide sounds better, but none grip better than the Furutech.

No locking types I am aware of. Get a tight fitting connector. Wattgate is another one to consider.
Thanks for responding you guys. It amazes me sometimes how much time/money/effort is spent tweaking/designing audio stuff to reach "state of the art" reproduction and then simple/no brainer/obvious stuff doesn't get addressed. The balanced IC's snap in, why not the PC's!
There are some solutions out there. Unfortunately most require some modifications.
