Coupling device for restraining belts, particilarly for children safety seats for motor vehicles

摘要

A coupling device ( 20 ) for restraining belts, particularly for children safety seats for motor-vehicles, comprises a body ( 21 ) intended to be connected to at least one belt branch and a pair of tongue elements ( 10 ) intended to be connected each to a respective belt branch. Each tongue element ( 10 ) includes an attachment portion ( 10 b) for connection with the respective belt branch and a stem portion ( 10 a) arranged to be received and locked in the body ( 21 ) and forming a catch tooth ( 10 c) for locking the tongue element ( 10 ) in the body ( 21 ). Each tongue element ( 10 ) further comprises a metal insert ( 12 ) wholly covered by a plastic or rubber housing or coating. Thus, the risk of burnings in case of the coupling device being handled after the vehicle has been left in the sun for a long time is prevented.
