The invention relates to a pivoting pin (1) for use on scaffold vertical frames (6) as a connecting element for scaffold bars and braces extending in horizontal and/or vertical direction, having a sleeve-like support (2) that may be welded on the vertical frame (6), which support on its bottom has a slot (3) extending in longitudinal direction which is larger in width than a fall bar (5) fitted with a bearing in the interior of support (2) and pivoting around a horizontal axis, which fall bar protrudes downwardly from the slot (3) when in its vertical lock position and may be pivoted out of same solely towards the welded end of the support (2) in the interior thereof to reach its horizontal open position, the pivoting angle being confined to about 90°. In order to ensure functional security, particularly when exchanging or replacing the fall bar (5) under unfavorable ambient conditions on the building site, the invention suggests that the slot (3) be closed at its front, the fall bar (5) coming to a stop at the slot front wall when pivoted in forward direction into its lock position.
