A contact element for insertion in an insertion direction into a contact chamber of a plug-in connector. The contact element includes a housing extending in the insertion direction. The contact element furthermore includes a latching element connected to the housing, for latching into the contact chamber of the plug-in connector. The latching element has a cantilevered end region, the cantilevered end region having a first portion and a second portion connected to the first portion. The first portion extends oppositely to the insertion direction, or the first portion points obliquely outward from the housing oppositely to the insertion direction. The second portion is bent over inward with respect to the first portion. At least one support element is provided between the first portion and the second portion, which element braces the second portion against the second portion upon said application of force onto the latching element.
