The invention relates to a contact element (2) for electrically contacting an electrical conductor (4) to a connection part (40) of an electrical system (42), in particular an electrical system of a motor vehicle, with the electrical conductor (4), which is sheathed with a conductor insulation (6), and with a cable lug (10, 10′, 10″, 10′″), which is connected in an electrically conductive manner to the electrical conductor (4) and comprises a contact part (11), wherein the cable lug (10, 10′, 10″, 10′″) and a section (14) of the electrical conductor (4) attached thereto are overmoulded with an electrically insulating housing (16) in such manner that a part (17) of the contact part (11) is exposed, wherein the housing (16) has a channel (20, 26), which runs from an opening (22, 28) of the housing (16) to the exposed part (17) of the contact part (11), and wherein a sealing element (30) is injection-moulded onto the housing (16) to seal a closure (44, 34), in particular a cover (34), which can be used to close the opening (22, 28). The invention further relates to a method for producing such a contact element.
