An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. The pair of inner housing retaining surfaces can engage the pair of cooperating inner housing retaining surfaces, with the pin retaining receptacle of the inner housing extending into the interior of the outer housing, to slidably couple the inner housing and the outer housing together while permitting movement of the inner housing relative to the outer housing in a Y-direction in response to the inner housing moving in the Y-direction during insertion of the pin into the pin retaining receptacle. Associated methods are also disclosed.
