Default Bell rings when garden gate opens?

My small city garden has a standard Victorian railing

A few days ago someone came in the garden and stole
a (locked) bike.

This made me wonder if there is any simple way
to make a bell ring when the gate is opened?

Also, is there a standard spring which will
keep the gate closed?

ISTR adam was rigging up something similar very recently - google on
uk.d-i-y for "reed switch changeover" and see if it comes up if not
ask Adam (ARWadsworth) for an update?
