<p>The slider (5) has a planar base (5a) and a front nose (5c) with flaps fitted over a standing roof seam. The nose is provided internally with two lugs (5e1, 5e2) folded on themselves and penetrating partly into an inner volume formed in the nose. One of the lugs bears against a wall facing one flap, and the other leg bears against an opposite face of a flap of a next panel, where the elasticity of the legs locks the slider in a position relative to the standing roof seam. Projecting portions are arranged on flaps (5b) of the base and oriented opposite a rear face of the base.</p> |
