Electric connector

An electric connector including:

• a housing including a plurality of partition walls and having a plurality of cavities partitioned said partition walls, a terminal being inserted into each of said cavities, said housing being formed with at least one retainer insertion hole formed through a sidewall of said housing and said partition walls in a second direction perpendicular to a first direction in which said terminal is inserted into each of said cavities;
• and
• a retainer for inserting into said retainer insertion hole for engagement with said terminal in said housing,
• said retainer including:
• a surface with which said retainer makes contact with said retainer insertion hole, and
• at least one projection formed on said surface, said projection passing over at least one partition wall among said partition walls, and being engaged with a particular partition wall among said partition walls,
• said projection being elastically deformable in said first direction
• said partition walls situated in said second direction to the rear of the partition walls with which said projection is engaged, being formed with a cut-out such that said partition walls do not block said projection passing through said retainer insertion hole when said retainer is inserted into said retainer insertion hole,
• said surface of said retainer making contact with a sidewall of said retainer insertion hole and further with one of more sidewall(s) of said cavities,
• said projection partially defining a width of said retainer in a direction perpendicular to said second direction.
