Abstract
In a lance defect detection construction, if a lance lacks a beak at its distal end because of defective molding, the lance can not be displaced by a distal end of a terminal. In such a case, an insertion prevention surface, which is so arranged as to interfere with a retaining piece portion of the terminal, formed on a rear edge of each of side beaks formed respectively on opposite side surfaces of the lance, abuts against a front edge of the associated retaining piece portion, thereby hindering the insertion of the terminal into a terminal receiving chamber 1. As a result, the terminal is held not in a pseudo-retained condition but in an clearly incompletely-inserted condition, so that a molding defect in the lance can be easily detected.
