In an electric connector on a printed circuit board ( 20 ) that features a connector part ( 1 ) acted upon with relatively high electric voltage values, sparkovers between the continuing strip conductors arranged on the printed circuit board and the soldering points ( 22 ) of the electric contacts ( 8 ) are prevented by providing a snap-on element ( 10 ) with several chambers ( 13 ) in the connector part ( 1 ), wherein the chamber walls ( 12 ) of this snap-on element can be inserted into slots ( 23 ) arranged in the printed circuit board ( 20 ), and wherein the chambers respectively enclose the soldering point of one of the electric contacts in the connector part.
