Flat contact portions having respectively a converging contact point which projects inward are formed at the free ends of the spring tines. Since a pair of the spring tines are formed so that two lines linking the converging contact points opposite to each other with respect to sections thereof are substantially orthogonal, it is possible to precisely and easily measure the distances between the contact points of the spring tines to define an opening for receiving the pin contact.

The guide mechanism causes one of the connectors to gradually approach and fit with the other connector until a throughly fitted condition is reached. Only when the connectors are at the predetermined position, a flexible grommet for the one connector can be fixed by way of a fixing element to a panel or the like to which the fixing frame is secured.
