The K-mount adaptor mounts flush and as such can't be locked into the K mount 
like a conventional K lens (screw lenses don't lock either). In order to 
prevent the K-mount adaptor from falling out of the body (with the screw lens 
attached) it is furnished with a small locking spring that fits into one of the 
K bayonet keys. As such it can only be released from the K mount after the lens 
has been un-screwed.

Moral of the story: Don't Super Glue your K-mount adaptor onto your screw lens 
(without suitable modifications of course) :-)
