Abstract
An angle accessory for skirting ducts includes two flaps mounted to pivot about a pivot axis via assembly structure including two male engagement elements on the first flap and two female engagement elements on the second flap. In the vicinity of the male engagement elements, the first flap has at least one flange projecting from one of its end edges and forming an obstacle that co-operates with at least one lip of the first flap to define at least one passageway giving access to at least one male engagement element, the passageway having a small height constraining the flaps to be assembled together by bringing the second flap towards the first flap while tilting the second flap relative to the first flap's pivot axis, and then by straightening up the second flap along the pivot axis so as to engage successively the female engagement elements over the male engagement elements.
