Without primary locking
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. 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.
