Seems to me that the opposite of "attach" is "detach", not "clear".

Or "remove", perhaps...

Actually, "detach" is better - neither "clear" nor "remove" imply "... and give
me what used to be attached there", as this thing is doing.

Ok, seems we have reached the agreement about the new name ;-), will 
follow the instruction.
