Abstract: A joint assembly of a television cabinet or similar structure is formed by inserting a panel member in a groove formed in a receiving member. A fastener clip, inserted in the groove, engages both the panel member and the receiving member and holds them together. The fastener includes a generally planar body portion arranged to abut a sidewall of the groove. The fastener has at least one deformable section generally directed at an angle to the body portion toward the interior of the groove and flexibly affixed to the body to oppose motion toward the body portion. Each deformable section includes at least a first biting projection extending in a direction generally toward the interior of the groove. Each deformable section also includes at least a second biting projection extending in a direction generally opposite to the direction of the first biting projection.
