The Deafmetal® Tube Fastener is a specialised accessory designed to securely attach Deafmetal safety jewellery to compatible hearing devices, including the Cochlear Kanso® 2 and Kanso® 3 sound processors. Developed for devices that use a fish‑line style attachment system, this fastener offers a discreet and reliable connection point while maintaining everyday comfort and usability.

Designed with both functionality and simplicity in mind, the Deafmetal® Tube is supplied ready‑to‑use with the Cochlear safety line, allowing you to easily connect a variety of Deafmetal jewellery pieces. These include earrings, safety chains, and safety rings, enabling users to personalise their hearing device setup while improving security.

✔️ Designed specifically for Cochlear Kanso® hearing devices
✔️ Compatible with fish‑line style attachment systems
✔️ Works with Deafmetal® earrings, safety chains, and rings
✔️ Lightweight design for comfortable everyday use

For optimal comfort and fit, it is recommended to pair the Deafmetal® Tube with a Deafmetal® earring or safety chain measuring between 7–15 cm, depending on the distance between the ear piercing (or cuff) and the hearing device. The Tube can also be used with a Deafmetal Safety Ring cuff, offering a convenient non‑pierced option, provided the ring has a compatible chain‑link attachment.

This fastening component plays an important role in creating a secure and adaptable hearing device accessory system. Please note that Deafmetal® jewellery items are sold separately, and the Tube is typically used as part of a complete configuration.

Each Deafmetal® component is sold as a single piece, reflecting the needs of users who require only one attachment. The Deafmetal® Tube Fastener provides a practical solution for improving both the security and personalisation of your hearing device accessories.
