Abstract: Provided is a connector designed for double retention of a terminal fitting, which inhibits flexure of a flexible lance retaining the terminal fitting by pushing a front holder from a temporary retention position into a full retention position. The connector includes at least any one of abutting planes of a retaining protrusion and a retention arm performing temporary retention of the front holder, as an element to strengthen retention when pushing force is applied to the front holder. Specifically, said abutting plane is formed as an inclined plane with an angle in a direction of generating bites upon application of pushing force. And the connector is designed to effectuate release of retention by means of inserting a retention release jig from a front side of the connector housing.
