Abstract
A coupling is provided for attaching an evaporative emission device having a housing to a mounting surface of a motor vehicle. The coupling includes a pair of tracks fixed the mounting surface and a pair of matching rails fixed to the housing. The rails are sized to slide within the tracks until reaching a predetermined seated position within the rails. An aperture is fixed to the mounting surface and includes a shoulder with a manufacturing tolerance defined about a nominal location at the predetermined seated position. A resilient latch is formed on the housing and located so as to snap into the aperture at the predetermined seated position. The latch includes a inclined engaging surface to engage the shoulder over the entire tolerance range of the shoulder.
