Pull through contacts and receiving sleeves within a connector insulator cooperate to permit the contacts to be inserted into the sleeves of the insulator in either direction and to be held there by interference between laterally extending, coined portions on the contact of a bellows type and the walls of the sleeve. Card edge connector contacts are formed from square wire stock by coining a central portion of each contact into a press fit region and a pair of lower alignment ears. The receiving sleeves formed in the insulator are constructed to permit the contact to be initially top loaded therein and held in position within the insulator by means of engagement of the lower ears on the contact with the side walls of the sleeves. Once the connector of the present invention is assembled to a mounting substrate by pull home press fitting of the contacts, the insulator may be removed by lifting upwardly to overcome the frictional engagement between the contact ears and the side walls of the sleeves to expose the contacts free standing in the substrate for subsequent repair thereof.
