This invention provides a contact stop for an electrical connector of the type having front insertable contacts. The invention is characterized by a plate (40) of hard dielectric material located adjacent the rear face of a contact retaining insert (30). The plate (40) has a plurality of passages (41) each of which terminate at one end in a forwardly extending solid wall tubular tower (42) which has a forward end or a shoulder (43) which abuts against a rearwardly facing shoulder (23) on a contact (20) in the passage (31) of the insert (30) to limit rearward movement of the contact after it has been inserted into the insert (30).
