SecureSleeve slip-on sleeves and IEC-LOCK connectors for secure IEC power connections

For IEC 60320 power connections, there are various options available to make it more difficult or to mechanically prevent the connector from becoming disengaged unintentionally. DINIC SecureSleeve slip-on sleeves are fitted onto existing C13, C14, C19 or C20 connectors and increase their retention force. IEC-LOCK connectors, on the other hand, feature an integrated mechanical locking mechanism and are suitable for applications where the locking function is to be an integral part of the connector itself.

Both solutions are used in particular in data centres, server rooms, IT racks, PDUs, UPS systems, industrial installations, and in media and event technology. Which design is appropriate depends on whether an existing cable is to be retrofitted or a power connection with an integrated locking mechanism is to be used.

SecureSleeve – retrofitting existing connectors

SecureSleeve slip-on sleeves are fitted directly onto the corresponding IEC connector on the cable. This allows the holding force of existing power cables to be increased without having to replace the entire connection or extension cable.

For C13, C14, C19 and C20
Can be retrofitted without tools
Existing cables can continue to be used
Increased holding force of the connector
Depending on the variant, can also be used for colour-coding

IEC-LOCK – integrated mechanical locking mechanism

IEC-LOCK connectors feature an integrated locking mechanism. The locking function is therefore already an integral part of the connector. This is particularly useful for new installations or applications where electrical connections need to be specifically protected against accidental disconnection.

Integrated mechanical locking mechanism
No separate locking element required
For professional IT and industrial applications
Suitable for servers, PDUs and UPSs
Alternative to the retrofit SecureSleeve solution

Which SecureSleeve slip-on sleeve is suitable?

The designation of the SecureSleeve slip-on sleeve depends on the connector onto which it is fitted. The correct version can therefore be determined directly from the existing cable.

SecureSleeve	Fits onto	Typical connection
C13	IEC 60320 C13 female connector	C13 ↔ C14
C14	IEC 60320 C14 plug	C14 ↔ C13
C19	IEC 60320 C19 socket	C19 ↔ C20
C20	IEC 60320 C20 plug	C20 ↔ C19

Want to reuse your existing cable?
Then a suitable SecureSleeve slip-on sleeve is usually the obvious solution.

Do you require an integrated locking mechanism?
In that case, an IEC-LOCK connector provides the locking function directly within the connector.

SecureSleeve or IEC-LOCK: Which safety device is suitable for your power connection?

An accidentally disconnected power connection can lead to operational disruptions in server rooms, data centres, industrial facilities and other technical installations. SecureSleeve slip-on sleeves and IEC-LOCK connectors offer two different solutions for IEC 60320 power connections.

The key difference is that SecureSleeve is fitted onto an existing connector to increase its retention force. IEC-LOCK, on the other hand, features an integrated mechanical locking mechanism. This means it can be used for existing installations as well as new power connections where a locking function is specified from the outset.

SecureSleeve – flexible retrofitting

SecureSleeve is particularly suitable when existing IEC connection cables or extension leads are to be reused. The appropriate sleeve is fitted onto the relevant C13, C14, C19 or C20 connector and increases the holding force of the connection.

Existing cables can continue to be used
Tool-free installation
For C13, C14, C19 and C20
Increased holding force
No mechanical locking required
Colour coding available depending on variant

IEC-LOCK – mechanically locked electrical connection

IEC-LOCK connectors feature an integrated mechanical locking mechanism. The locking function is therefore an integral part of the connector itself and does not need to be retrofitted as a separate component. IEC-LOCK is particularly suitable for professional applications where a power connection needs to be specifically secured against accidental disconnection.

Integrated mechanical locking
No additional locking element required
For new and professionally planned installations
Suitable for servers, PDUs, UPSs and industrial applications
ideal for hard-to-reach power connections

A direct comparison of SecureSleeve and IEC-LOCK

Feature	SecureSleeve	IEC-LOCK
Operating principle	Increases the holding force	Mechanical locking
Retrofitting to existing cables	Highly suitable	The connector is selected in the IEC-LOCK version
Additional locking component	Slip-on sleeve	No, integrated locking mechanism
Colour coding	Possible depending on the version	Not a primary function
Typical choice	Reuse existing cable	Locking mechanism integrated directly into the connector

Where are SecureSleeve and IEC-LOCK used?

Secure IEC power connections are particularly useful where accidental disconnection of the power supply needs to be prevented. Typical areas of application include servers and network components, storage systems, PDUs, UPS systems, IT racks, industrial plant, and media and event technology. SecureSleeve offers a flexible option for retrofitting existing connectors. IEC-LOCK is particularly suitable where a mechanical locking mechanism is required directly within the connector.
