Abstract
A portable telephone assembly comprising first and second portions arranged to be mutually detachably interconnectable is disclosed. The second portion is arranged to be removably attachable to a user. The first portion comprises a body portion and an extendible portion movable between a relatively extended configuration and a relatively contracted configuration. The extendible portion is biased towards the relatively extended configuration, such that when the first portion is detached from the second portion, the extendible portion is urged towards the relatively extended configuration.
