Half-fitting prevention connector

A half-fitting prevention connector comprising:

• a first connector housing having a lock arm including a leg portion provided at an intermediate portion of said lock arm between a front end portion and a rear end thereof and extending to a housing body of said first connector, said lock arm pivotally movable on said leg portion serving as a fulcrum;
• a second connector housing having an engagement portion engagable with a lock portion of said lock arm, and fitted relative to said first connector housing;
• a fitting detection member pivotally mounted on said first connector housing in a lever-like manner;
• and
• a detection member-limiting portion provided at said rear end of said lock arm;
• wherein said detection member-limiting portion prevents a pivotal movement of said fitting detection member when said lock portion and said engagement portion are not in an engaged condition, and
• said fitting detection member is inclined when a rear end of said fitting detection member is pressed down by said detection member-limiting portion before an engagement of said lock portion with said engagement portion is completed, so that a front end portion of said fitting detection member is pivotally displaced outwardly from said housing body of said first connector housing.
