Without primary locking
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Some combinations of housing/cable terminal have no primary locking with lockable lock catches/locking tabs.
The cavities in the housing in these cases have integral catches which hold the cable terminals in place. When the secondary locking on the housing is opened the cable terminals can be lifted out. No terminal removal tool is needed.
An example is a housing with moisture proof cable terminals.
