(57) Upstanding polysurfaced male and female lips are provided along confronting edges of adjacent elements, such as building panels. The female lip is engaged over the male lip and when rotated about the male lip is snap-fitted into interlocked relation therewith. The lips provide an upstanding joint which secures the adjacent elements in fixed angular relation to each other. The lips are interengaged along plural angularly spaced-apart regions and are overlapped such that vertical and lateral disengagement of either lip relative to the other is precluded along the entire length of the joint.
