Connector

A connector, comprising:

• a housing having front and rear ends and at least one cavity formed therein, and two first displacement restrictions formed on opposed inwardly facing surfaces of the housing that are fixed relative to one another and parallel to an assembly direction;
• at least one terminal fitting to be inserted into the cavity in the assembling direction;
• at least one locking lance disposed in the housing to be deformed and retracted out of an insertion path for the terminal fitting in the process of inserting the terminal fitting and resiliently returning to retain the terminal fitting when the terminal fitting is inserted properly into the cavity, the locking lance being spaced from the first displacement restrictions;
• at least one deformation space open on the front end of the housing and allowing deformation of the locking lance;
• and
• a front retainer assembled to the front end of the housing and including a front wall substantially facing the front end of the housing in an assembled state, at least one detecting portion fit into the deformation space in the assembled state, and two oppositely facing second displacement restrictions on outwardly facing surfaces of the front retainer that are parallel to the assembly direction and fixed relative to one another;
• wherein the two second displacement restrictions contact the two first displacement restrictions in directions crossing the assembling direction as the front retainer is mounted on the housing for restricting relative displacements of the housing and the front retainer in the direction crossing the assembling direction.
