Exactly the idea behind Apple's magnetic power supply connectors.
It's the Schuko the only one safe power connector option ?

I know this from other situations, I have connected my headphones via lockable Neutrik stereo 6.3mm socket. Not a good idea, if something goes wrong, the cable breaks instead of just the jack plug is flying out.

It would seem to be a good solution,
It would remain to fix the other part of the cable,
probably the ones most exposed to the problem
are the active studio monitors,
and the active live speakers,
because lot of vibrations received by low frequencies generated,
(bass gtr & kick drum)
(check how many active studio monitors have no lock on the amplifier power in connector , placed in the back side of the monitor)

I have this in mind when writing my comment, save my laptop few times...
There is also the lock for DC plug on various synth/keyboard... I never lock them !
This also work for guitar and amp...
Anyway if you make the wrong move you cut everything, stage or studio... but if you get cable loose you just lost signal and it's a 3 sec fix, if something fall or break the fix is not the same.
In my youth I get used to coincidently lock the guitar jack in the strap, and make a loop on the amp handle (to not have the cable failing around the mic stand), hopefully never get a catastrophic result, but it was not that smart...
For high current connections NEMA L6-30P connectors are used, which is a quarter-turn twist lock.
There are several locking variants of standard NEMA connectors, all the ones with L designation:
NEMA connector configurations
Can I paste in SVG files directly? Seems so...

Interesting - I thought the only locking connectors were 240v.
Do yo not use these commando type mains connectors in the U.S
https://cpc.farnell.com/walther/210306/16a-2p-e-free-plug-240v-blu/dp/CN00151?st=16a plugIn the U.K there is a yellow coloured version that is used mainly on building sites that is for 115v.

Not domestically, but I have seen them used for 208V or 240V in datacenter power distribution to racks.

In 35 years of doing location recording, I've never seen a locking 120v AC outlet in any facility I've worked in (churches, concert halls, theaters, auditoriums, etc.).
Looks good. Not seen these previously. Although I can't actually see how they work !

I have used these and keep at least a dozen in stock to fit as needed. They are actually brilliant, the lock is like a backwards facing “tooth” that grabs the iec prongs in the socket, so its very secure and doesn't require a special socket to work (yes, there are locking IEC sockets and cables but they’re a cheesy plastic latch thats easily broken))
When you pull back on the red tab it both releases the teeth and pulls the cable free.
Unlike any other IEC wiring device, it actually has machined brass terminations internally, not some crappy stamped or folded steel and screw arrangement. They’re very nicely built.
The only downside is they are fairly long, definitely longer than a molded IEC so if space behind is a concern they may cause problems.
Otherwise i agree, powercon is the best overall solution.
They hold onto the Earth pin. It's pretty effective.
That first pic looks like a telex phone line connector to me.
Hi r2d2,
From the 1960s to the 1990s, Tuchel T2260 plugs were widely used in German broadcasters to meet high safety requirements:

https://www.ebay.de/itm/17449910425...55-0&campid=5338722076&customid=&toolid=10050
Of course you also need the corresponding socket:

I never ever up to this day had or seen a Schuko male connector disconnect alone, by vibration or by accident from a female Schuko. The physical connection between male and female Schuko is quite strong and safe.
Standard IEC connectors, specially the cheapest ones are prone to just fall by themselves due to vibration and pressure, it's a classic.
The solution is a IEC connector with a Lock like Rod Flinn showed,
Powercon is a good connector but my Live sound mixing consoles, computer, power amps, Stageboxes, etc etc, all come with IEC connectors installed from the factory, so Powercon is not a solution for these, but a lockable IEC connector solves it
I use the exact same ones as in Rob's link and they work great
As for the connection to the Wall, if there's a female Schuko installed in the wall then Schuko works great and doesn't fall ever by themselves

I suppose you could mount an 'output' powercon socket in your walls. Like the one used for linking lightning devices. They are almost the same as the 'input' version, but reversed...
But i have yet to see a wall plug getting loose from its socket. While i've seen people rip off the socket from the wall by walking on a cable.
I like iec locks for devices installed in touring racks. They tend to get loose during transport and it can be a pita to replug them all before a show.

Sincerely thanks so much for all post !
As short summary,
seems that something suitable/adaptable is available,
(...although not fully specific)
and a solution could be
the cable with "IEC-C13" female on the device side,
but it require to replace the male one on the panel of the device ?
and a speakon type on the other side of the cable,
however, that needs its own box where the panel model should be placed,
and the same for where the box cable will then go to connect ,
(If not directly connected to a power distribution box, with dedicated on-off switch)
@gyraf:
Actually those power connectors really looks to be not the best in terms of safety.....
@ursonate:
They inspire "trust", although like the speakon they need appropriate box for the females,
what kind of connectors were they replaced with ?
any more post about is welcome,
more thanks guys !

I should grab a pic of the internals today at the shop. Its really quite well built.
Also iirc i think they have a gripper on all 3 pins, but i could be mistaken.
I believe, in this case you are mistaken. I have one in front of me & when you oull the red release back you can only see something happening in the Earth pin hole.
