We had some cords that could get pulled out in a couple of data centers,
and we ended up rigging a "holder" of sorts with zip-ties. Made it a
PITA to pull the occasional cord, but we never had one fall out, and we
didn't have to resort to someones proprietary cord lock.

Visual aid:
My colleague went there today because two servers were both
intermittently reporting loss of AC input on one power supply. Both
were in the same PDU and both were loose. He checked all the other
cords while he was there and found a few other loose ones. He
mentioned it to one of the data center employees who said we should
get “V-Lock” cords.
I’ve /never/ seen one of those IEC power connectors fall out by
itself, so it’s bizarre that multiples did simultaneously. I looked
up V-Lock and it’s apparently a proprietary locking mechanism by
Schurter. Apparently V-Lock receptacles have a cutout on the inside
of the wider flat side of the connector….the side which is usually up
on a PC. A V-Lock cord has a tab that clicks into that cutout, and
you have to press a button to release the tab. I don’t have the APC
model number, but the cluster of six C13 receptacles on the APC PDU
does look exactly like this item from the Schurter catalog:
https://www.schurter.com/en/datasheet/4751. So it probably is a V-Lock.
So locking cords sounds great, but I’ve never needed one before. Do
the locking receptacles have less holding power than the normal IEC
ones? I’m thinking maybe that cutout could let the plastic socket
spread out more than normal.
