Those are part of the Slot1 retention system.

When an actual Intel Slot1 processor module is inserted, the clips snap into the sides of the module, and it wont come out until you play silly games with the clips.

The clips only fit the Intel slot1 packages, not slotket adapters.

Probably just the wrong type. These brackets could be easily replaced with 2 screws each attaching them to the board.
There are universal brackets that can stay snug on all variations of the SECC1/2 cartridges and the bare PCB CPU modules with heatsink with wings types (tho not the myriad of slotkets).
Most included brackets were not the universal type.

It's not a big deal unless you regularly transport your computer upside down. The force of the slot1 cartridge connector itself is generally pretty good.

Yeah, I watched a video showing those two clips at the sides, but mine doesn't have those. So, are the CPUs I have not actual Slot 1 processors...? But slotkets? I was under the impression they were Slot 1. Or is it some sort of hybrid?

It does make it easier to switch between my PIII and PII, but it would just be nice to understand why they never lock. And maybe get something more suitable.

Slot 1 is the slot specification used by Pentium II and certain Pentium III and Celeron processors. The processors encased in the black plastic case is known as SECC (Single Edge Contact Cartridge).

Celeron processors typically used the SEPP (Single Edge Processor Package) which lacks the black plastic case. But they are still slot 1 processors.

Slotkeys are converters that allow a socketed processor (typically Socket 370) to convert to a Slot 1.

I see. So what I have are Slot 1s. I just don't have the right brackets.
