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.

Abstract: An angle connection accessory is to be disposed at the junction between at least two skirting ducts extending in different directions. The angle connection accessory includes a plate having: a web; an inlet side face and an outlet side face that extend perpendicularly to at least one partition that is perpendicular to the web and that mutually isolates a first compartment and a second compartment; and an outlet face parallel to the partition via which firstly the first compartment opens directly to the outside, and secondly the second compartment also opens to the outside via a channel isolated from the first compartment and extending substantially perpendicularly to the partition between the second compartment and the outlet face. The plate includes two flaps hinged relative to each other via a hinge so as to form an angle between them, the channel extending at the join between the two flaps.

Abstract: The invention relates to an angle accessory for skirting ducts, said angle accessory comprising two flaps mounted to pivot about a pivot axis via assembly means comprising two male engagement elements on the first flap and two female engagement elements on the second flap. According to the invention, in the vicinity of said male engagement elements, the first flap is provided with at least one flange projecting from one of its end edges and forming an obstacle that co-operates with at least one lip of said first flap to define at least one passageway giving access to at least one male engagement element, said passageway having a small height constraining said flaps to be assembled together by bringing the second flap towards the first flap while tilting said second flap relative to the pivot axis of the first flap, and then by straightening up said second flap along the pivot axis so as to engage successively said female engagement elements over said male engagement elements.
