A slippage preventing locking furniture fastener, method of making same, and a joint structure which includes a flexible locking clip and shouldered screw. The clip has a raised central portion having an inclined slot therein which is connected to a furniture piece by securing flanges. An internal locking flange extends at an upward angle toward the raised central portion and terminates below the slot, adjacent the head of a shouldered screw received in a seating area. The free end of the locking flange is wider than the slot to prevent the locking flange from passing through the slot or allowing the joint to loosen, even when substantial force is applied to the joint including the clip. A method for forming the clip is also disclosed including cutting a configured tab in a metal blank and bending the blank. The bending includes positioning the tab as a locking flange with its free end adjacent a narrower slot portion in a raised central portion. The slot is defined by at least a portion of the outline of the configured tab.

A clip for use in a joint structure comprising: a unitary, one piece plate having an end flange means for securing the clip in a joint structure; a first central portion generally in a plane spaced from the general plane of said end flange means, and having joining means for joining said end flange

A clip for use in a joint structure comprising: a unitary, one piece plate having an end flange means for securing the clip in a joint structure; a first central portion generally in a plane spaced from the general plane of said end flange means, and having joining means for joining said end flange means to said central portion; first slotted means for receiving the head of a securing stud in said first central portion, said slotted means including a narrow slot area with a closed end and seating means for seating the head of a securing stud in said slotted means, said slotted means having an intermediate slot area communicative with said narrow slot area, said seating means including a portion of said narrow slot area; inclined means for drawing a securing stud downwardly when the stud is moved along the slot toward the closed end; and a locking flange integrally formed with said plate and bent to extend rectilinearly generally from said end flange means at an angle to said slotted means, said locking flange terminating at a locking end adjacent said seating means at said narrow slot area and at a distance from said central portion less than the thickness of a securing stud head, said locking end being wider than the width of said narrow slot area but not being wider than the width of said intermediate slot area, whereby the head of a securing stud can depress and pass said locking end of said locking flange as it passes toward said closed end of said slot but is prevented from returning past said locking end when moving away from said closed end such that slippage of the locking end of said locking flange through said slot is prevented and slippage in and/or loosening of any joint in which the clip is used is reduced and/or prevented.
