The invention has an object to provide a connector 10 which achieves a reduced overall height of the order of 1.0 mm and space-saving substrate (in the inserting direction of a circuit board) and which obtains stable connection with a slight operating force and does not cause any defective connection even if a connecting object is accidentally subjected to an external force. The object is accomplished by a connector comprising substantially H-shaped contacts 14 each including a first piece 28 having a contact portion 32 and a pressure receiving portion 34, a second piece 30 having a contact portion 32 and a connection portion 36, and a jointing portion 38 connecting these first and second pieces, and further including holding device permitting pushing portions 48 of a pivoting member 16 to pivotally move between the pressure receiving portions 34 and the connection portions 36, a housing 12 having a ceiling portion 20 formed at least at both ends with protection walls 22 for preventing the ceiling portion 20 from being upwardly deformed when the connecting object is accidentally forced upwardly, and the pivoting member 16 including the pushing portions 48, anchoring holes 50 independently from one another and an actuating portion 46 which is pivotally moved toward a fitting opening 18 of the housing 12 to bring the contact portions 32 of the contacts 14 into contact with the connecting object.
