Fig. 2 shows in perspective the security chain disabled.
Refering to the drawings the security chain comprises, a security chain 6 and a secure self releasing anchorage housing 2 releasably secured to the housing by, for example solenoid, catch or similar (not shown) In order for the end of the security chain 1 to be released as shown in Fig 2. The solenoid 4 is activated or de-activated.
To re-secure the security chain the feed to solenoid 4 Fig 2 is reversed.
