DECYOOL 12-F657-F1993 Locking Pin Backs, 55-Piece Nickel-Plated Copper Set

Some pin wearers want a simple replacement back, others want a lock that can help keep a pin attached during regular wear. DECYOOL’s metal pin backs use a spring-loaded clasp and release without tools. The 55-piece set is made for standard pins, badges, and brooches.

Quick overview

Each keeper is made from nickel-plated copper with a silver finish. Its spring-loaded mechanism secures onto a pin post when pushed into place, and the base pulls back to release it. That tool-free action is useful when changing pins between jackets, bags, hats, or uniforms, and the low-profile shape sits behind the pin rather than adding a bulky fastening point.

The backs measure 0.39 inches in diameter and 0.24 inches in height. A 55-piece pack gives collectors and people who wear several pins a set of replacements to keep on hand. Compared with basic rubber or butterfly clutches, this locking style offers a metal, spring-loaded fastening approach, choose it when a dedicated locking clasp suits the way you wear or swap your pins.

How it fits

These keepers are designed for standard pin posts and can be used with enamel lapel pins, brooches, insignia, military badges, name tags, citation bars, lanyards, hats, and vests. They also suit pins worn on jackets and backpacks, so one pack can serve different everyday setups. The small, flat back is intended to sit discreetly behind a pin while helping cover the exposed post.

Buyers commonly describe the backs as helpful for keeping pins in place and appreciate their appearance across items such as bags and uniforms. Feedback on operation is mixed: some find the locking action secure, while others say the backs can be difficult to remove or do not lock as expected. For a pin you switch often, the push-on and pull-off release is a practical feature to consider alongside how firmly you want it held.

How to use it

Align a keeper with the pin post and push it on to engage the spring-loaded lock. To remove it, hold the pin securely and pull back on the base. No tiny wrench or other tool is required. This straightforward setup is convenient when attaching a pin to clothing or a bag, or when replacing a worn or missing back.

For a set of pins, keep the spare backs together so they are easy to find when changing accessories or preparing a uniform or outfit. Match each keeper to a standard pin post, then make sure it is seated before wearing the item. The silver, nickel-plated copper finish works as a discreet metal backing for a range of pin styles.
