My PetSafe® Safety Seatbelt Tether Will Not Release From My Car’s Buckle
The PetSafe® Safety Seatbelt Tether is NOT compatible with seatbelt buckles in Volvo vehicles or the Ford F-Series trucks. The tether will become stuck and will not be able to be removed.

Gently push a flat knife into the retaining clip beside the attachment buckle.
Gently push down inside the buckle and simultaneously pull the tether out.
