The new IEC-lock and IEC-Lock+ power lead design provides a simple way of securing a power lead to any electrical appliance that uses an IEC type mains lead. As with most good designs the IEC-lock's patented locking mechanism is beautifully simple. The lead is simply connected to the appliance as any other IEC lead. Once the lead has been fitted the IEC-lock mechanism locks it to the appliance, ensuring that the lead cannot become accidentally disconnected.
