Connector with moving front wall

A connector, comprising:

• a housing with opposite front and rear ends, at least one cavity formed in the housing and configured for receiving a terminal fitting, the cavity extending to the front end of the housing, a lock formed at an inner wall of the cavity for retaining the terminal fitting;
• and
• a front wall mounted on the front end of the housing, the front wall having at least one tab insertion hole that communicates with the cavity, an operable surface exposed on an end of the front wall for detaching the front wall from the housing, wherein the front wall has at least one jig insertion hole for receiving a detecting pin for an electrical connection test, the front wall being movable between a first position where the tab insertion hole is displaced from the cavity and a second position where the tab insertion hole communicates with the cavity, whereby the detecting pin can contact a detecting portion of the terminal fitting through the jig insertion hole when the front wall is at the first position and whereby the tab can contact a contact point of the terminal fitting through the tab insertion hole when the front wall is at the second position.
