Electrical plug connector with spring tension clamp

An electrical plug connector having a lower part and a cover which form a housing. At least one terminal point having a receiving pocket is formed within the lower part and the cover. A sub-assembly including a spring tension clamp having an arcuate tension spring, for making contact with electrical conductors, and a conductor rail having a contact region for receiving a mating contact is positioned in the receiving pocket. The cover has an actuator passageway and an angled guide projection extending into the actuator passageway for guiding an actuating tool to actuate the clamp. The angled guide projection is constructed as a web, the arcuate tension spring of the clamp has an aperture, and the angled guide projection reaches through the aperture as the cover is engaged with the lower part placed over the contact sub-assembly.
