Volkswagen Golf Service & Repair Manual: Secondary locking element

The secondary locking mechanism is a housing catch (second line locking mechanism) that secures all the wires in one contact housing. If a secondary locking mechanism is fitted to a contact housing, this must always be opened or removed using the appropriate tool before releasing and pulling out individual crimp contacts.
The secondary locking mechanism is different in colour from the rest of the contact housing. This makes it easier to identify the secondary locking mechanism and clarifies its intended function.
The types of contact housing shown here are just a few examples to show the different functions of secondary locking mechanism.
