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. Centering protrusions of one housing can engage the other housing to initially retain the pin retaining receptacle of the inner housing in a central position within the interior of the outer housing in the Y-direction prior to insertion of the pin into the pin retaining receptacle. The other housing can be movable against the centering protrusion to permit the pin retaining receptacle of the inner housing to move out of the central position in the Y-direction in response to engagement of the pin against the entry ramps during insertion of the pin into the pin retaining receptacle.
