<p>A joining device for joining panels at right angles to each other, comprising an element having a head and a shank and adapted to be secured into one of said panels with said head and part of the shank projecting from an edge thereof, a holding member adapted to be fitted in a recess provided in a major surface of the other of said panels, said holding member comprising a plug-like body portion having an end face arranged to be exposed at said major panel surface and having an opening extending therein axially from said end face to receive and surround said head, an inward projection within said opening, and a securing member located within said body portion and adjacent to said opening, the securing member having a shoulder-forming portion and being so positioned within said body portion that the shoulder-forming portion forms a shoulder on the other side of the opening relative to the projection, the distance between the shoulder-forming portion of the securing member and the projection on the body portion being less than the diameter of said head so that said head can be inserted into said opening and then forced between the shoulder and the projection until the head snaps in behind the shoulder and the projection, said securing member being operable from said end face and effective when operated to engage said head to apply a force thereto in a manner to draw said head inwardly relative to said opening to tighten the joint formed by said panels.</p> |
