The terminology is "slotted" - the distant arm is "slotted" so that it cannot
be pulled off unless the home signal is also clear.  The lever can be pulled,
but the arm doesn't move.  If this is the situation, when the home signal is
cleared the distant comes with it.

I would suggest reading the signalling FAQ at
http://www.users.globalnet.co.uk/~keithn/signalli.htm
or visiting the "signal box" at http://trainweb.com/signalbox/
for information.  These are British sites, and although there were many
differences between British and Victorian practices, the basic principles are
the same, with respect to semaphore signalling at least.
