Connector having a symmetrical retainer for allowing insertion in an inverted orientation

A connector, comprising:

• a connector housing having a plurality of terminal receiving chambers and a plurality of elastic retaining lances respectively protruding into said chambers, adjacent pairs of said terminal receiving chambers being defined by a pair of first support walls and a second support wall interposed therebetween, said pair of first support walls each including first locking projections and said second support wall having second locking projections;
• and
• a retainer including a pair of first and second lock arms extending forwardly from a base portion thereof, each said first lock arm having a first retaining projection and each said second lock arm having a second retaining projection, wherein said retainer is moveable from a provisional position at which terminals are insertable into said terminal receiving chambers and respectively engaged by said retaining lances to a complete position at which said elastic retaining lances are prevented from being disengaged from said terminals by said retainer, wherein in one of said provisional and complete positions each said first retaining projection engages an associated one of said first locking projections and in another of said provisional and complete positions each said second retaining projection engages an associated one of said second locking projections and wherein said retainer is substantially symmetrical about a center line dividing said pairs of first and second lock arms so that said retainer can be inserted in an inverted orientation.
