Volkswagen Polo Service & Repair Manual: Secondary Lock

The secondary lock is a housing securing mechanism (second locking mechanism) that secures all wires in one contact housing. If a secondary lock is installed at a contact housing, it must always be opened or removed using specified tool before releasing and pulling out individual crimp contacts.
Secondary lock is distinguished by a different color from the rest of the contact housing. It simplifies recognizing the secondary lock and clarifies its function.
