"CONNECTOR AND METHOD OF PRODUCING IT"

The present invention concerns a connector 10 formed by removing a pair of front and rear shaping dies in forward and backward directions. The connector 10 includes a housing 20, a lock arm 40 provided displaceably relative to the outer surface of the housing 20 and adapted to hold a mating housing and the housing 20 in a connected state, pairs of front and rear curved surfaces 57F, 57R, coupling portions 51 connecting the lock arm 40 and the housing 20, front step portions 54F continuously extending forward from end edges 58F closer to the rear curved surfaces 57R out of end edges of the front curved surfaces 57F in a curving direction, rear step portions 54R continuously extending backward from end edges closer to the front curved surfaces 57F out of end edges of the rear curved surfaces 57R in a curving direction, and pairs of curved portions 59F, 59R facing forward and backward and provided at opposite end portions of the curved surfaces 57F, 57R in directions crossing the curving directions.
