摘要

A mounting element (ME) (1) with a base plate (11) and a through-hole (112) is designed to fit on one end of a lock (2) so that the through-hole in the base plate matches up with a key hole (21) in the lock. The ME also has a retaining area (13) open towards one end of the lock. An alarm actuator (4) fits in the through-hole but can be removed.
