Abstract: An engaging member including a reinforcing projection and a cut-out portion. A recess complementary to the reinforcing projection is formed in the inner wall of the deflection space which receives the engaging member when it is deflected. When the engaging member is deflected by the terminal, the reinforcing projection fits into the recess. Excessive deflection of the engaging member is prevented by the contact of the surface of the cut-out portion with the inner wall of the deflection space. The strength of the engaging member is assured by the presence of the reinforcing projection. Since sufficient deflection room for the engaging member is provided by both the deflection space and the recess, the thickness of the deflection space can be made smaller than in prior art connectors by the depth of the recess.
