A fastener clip assembly for forming a substantially concealed joint (1) between panels of furniture, a shelf assembly or the like (6,4) includes a pair of clips (10) telescopingly assembled with one another to form a joint which prevents rotation between the clips and joint members. The clips are secured to respective joint members and assembled with a portion of the second clip (16) received through the slot of the first clip (12) such that offset engagement sections overlap one another while a resilient, flexible inclined section on at least one, but preferably both, of the engagement sections draws the clips and joint members together. An engaging member which resists disassembly of the clips may be included.
