A connector assembly, comprising:

• a first connector having a first housing and a connector position assurance device;
• and
• a second connector having a second housing, the connector position assurance device positioned in a temporary caught position on the first housing when the first connector is not mated with a second connector, the connector position assurance device allowed to slide to a caught position in front of the temporary caught position in a mating direction when the first connector is completely mated with the second connector, the connector position assurance device assuring that the first connector is completely mated with the second connector in the caught position, the connector position assurance device has a pressed-back portion abutted by the second housing during mating and pressed back relative to the first housing if the connector position assurance device is positioned in the caught position when the first connector starts to mate with the second connector, positioning the connector position assurance device in the temporary caught position at a complete mating of the first connector with the second connector, the second housing has a pressing-back portion abutting against the pressed-back portion of the connector position assurance device positioned in the caught position at a start of mating and pressing back the connector position assurance device relative to the first housing until the connector position assurance device is positioned in the temporary caught position at the complete mating.
