As you know, the locking tab of RJ45 network plugs breaks very easily. Protect it from breaking, with some Sugru. Prevention is even better than repairing a broken plug.
Then, when you pull the cable through a cables salad, the tab will not get hung to eventually break.
One 5g pack of Sugru will make approx 8 plugs.
Step 1: What You Need
- Sugru pack (5g, approx 8 plugs)
- One toothpick (or a nail, a swiss army knife, ... or anything similar)
Step 2: Form and Place a Sugru Ball
Form a ball of the size of a big pea. Knead it for at least 30 seconds. Roll it.
Place it on the plug as shown.
Step 3: Stick It and Form It
Form it as shown to increase the contact surface with the plug.
Cover the tab by 1 millimeter. (Covering the tab more than necessary will make the plug difficult to release.)
Step 4: Press the Tab
Press slowly but firmly.
Step 5: Release the Tab
Unstick the tab, using the toothpick.
Press and release repeatedly, until the tab moves freely into its hole.
Step 6: Done
Let cure for 24 hours.
