An electrical connector assembly includes a sleeve having an upper wall, a base wall, and opposing side walls. The upper wall, the base wall, and the opposing side walls define an opening and an interior within the sleeve. The upper wall defines first and second resilient spring webs. The base wall includes a resilient bridge web having a first mating structure formed therein. A pin is configured for insertion through the opening of the sleeve and into the interior such that insertion of the pin causes flexing of the bridge web and the first and second spring webs. The pin has a second mating structure for engaging with the first mating structure of the bridge web to secure the pin relative to the sleeve. The connecting portions of the first and second spring webs form a joint which is welded to connect the connecting portions of the first and second spring webs.
