Yes, and it was pretty much a useless feature...

About 7 years ago somebody came to me because a Mac+ had been locked to a
desk by said device, and it needed to be moved (and for that matter it
needed to be repaired). Alas he'd managed to lose the key.

Now, I had ample evidence that he was allowed to move said computer, so I
descended to the computer room with my trusty long TX15 driver and some
other tools. Without removing the lock i undid the 5 screws on the back
and pusehed the guts out of the case. Then a bit of tweaking with a
screwdriver on the hooks on the sides of said hole enabled me to remove
the locking loop thingy without damage.

Then all I had to do was resolder the dry joint on the scanning yoke
connector and put the case back on. The machine was uncoupled from the
locking device without damaing either part.
