You've just received a beautiful gold bracelet. You admire it, you slip it onto your wrist... and when you try to take it off, nothing budges. You pull, it resists. Panic sets in: "Is it stuck? Am I going to break it?"
Stop. Don't force it.
What you have is a ratchet clasp (also called a box clasp). This is the standard in fine jewelry for rivière bracelets or chunky chains. It is designed so that NEVER It opened accidentally. Its resistance is normal.
Once you get the hang of it, opening it takes 2 seconds. Here's how.
⚡ In Brief: How to open a ratchet clasp?
The 4-step method to avoid breaking anything:
Release the security measures : Open the two small arms ("figure eight") on the sides, if there are any.
Press Press the trigger (button/edge) firmly on top of the tab.
PUSH : Gently push the two parts towards each other (to relieve tension on the mechanism).
PULL : While keeping the button pressed, gently pull the tab outwards.
Understanding the Mechanism: What are we talking about?
A ratchet clasp is a precision mechanism made up of 3 parts. These parts must be identified to avoid pulling the wrong one.
-
The Box (Female) : This is the hollow part that contains the hidden spring.
-
The Tongue (Male) : This is the flat part that fits into the box.
-
The Safety Eight : It's the small metal arms on the sides that lock everything in place.
The golden rule: Never pull on the bracelet while the safety clasps are still closed. You will irreparably bend the metal.
Tutorial: Opening the Latch Clasp in 3 Steps
Here's the gentle method to open your bracelet without tools.
Step 1: Release the Security
Using your fingernail, lift the two small metal tabs located on the sides of the clasp. They should be fully open and away from the box.
Step 2: Activate the Trigger
Locate the small push button or raised lip on the top of the tab (the part that goes into the box). Press it firmly with your thumb to lower the internal hook.
Step 3: Pressure and Traction (The Secret)
This is where everything happens.
-
While pressing the button, PUSH Gently pull the bracelet towards the clasp (as if you wanted to close it further). This releases the tension on the internal spring.
-
Then gently pull outwards. The tab should slide out on its own, without forcing it.
Troubleshooting: My Clasp Has a Problem
Over time, gold (which is a soft metal) changes color. Here's how to fix the most common problems yourself, without going to a jeweler.
| Symptom | Probable Cause | Express Solution (Home) |
| The clasp no longer stays closed / opens by itself | The tongue flattened and lost its "spring". | Open the bracelet. With your fingernail, lift very slightly bend the end of the tongue upwards (0.5mm max) to restore its curvature. |
| The clasp is stuck / jammed | Dirt or oxidation in the internal mechanism. | Soak the clasp for 10 minutes in warm soapy water. Add a tiny drop of olive oil if needed to loosen it. |
| No distinct "click" on closing | Lack of tension in the tongue. | The same applies as for the clasp which no longer holds: give the tab a slight upward curve. |
Note: If the problem persists despite these tips, consult a jeweler. Never force anything with pliers.
Why is the ratchet clasp the best for 18k gold?
You might wonder why not use a simple carabiner? On valuable jewelry, a ratchet clasp is essential for three reasons:
-
Double Security: With the internal spring + the eight safety catches, accidental loss is virtually impossible.
-
Discretion: Once closed, the clasp becomes invisible and blends into the design (perfect for a diamond rivière or a massive bracelet).
-
Sustainability : It is a robust mechanism designed to support the weight of heavy jewelry for decades.
Now that you've mastered the technique, wear your bracelet with complete peace of mind!
