Abstract
A snap fit locking mechanism is provided for releasably joining a pair of components. The locking mechanism contains a resilient locking arm integrally formed on a first component. The locking arm includes an outwardly extending projection which defines a step portion and a cam surface. A rigid rectangular locking frame extends outwardly from a second component and defines a substantially rectangular aperture adapted to receive and secure the locking arm. A resilient tab extends outwardly from the second component and into the locking frame aperture and is deflected upon insertion of the locking arm into the locking frame aperture. The resilient tab maintains the locking arm in a secure engagement with the locking frame.
