Valve suitable for use in a relatively narrow elongate opening to an air duct in a window frame which opening faces inwardly towards an accommodation space. The valve has at least two, preferably three, separately made, elongate members made by extrusion. A first valve body-forming member and a second holder-forming member together with a third support-forming member are adapted to be pivoted relative to each other. In the closed position of the valve the members are adapted to support each other in triangular form over a substantial part of the length dimension of the valve. The first and second members are jointed together as a pair and the third member is jointed together as a pair with the first member as well as being adapted to make a snap-forming supporting abutment against the second member.

DETAILED DESCRIPTION I claim: 1.
A valve for an air duct in a window frame, said valve comprising a first member forming a valve body for closing off the air duct and including a rounded head portion at one end and a cavity spaced from said one end; a second member pivotally connected with said first member to define a holder and including an elongated cavity receiving said head portion of said first member in pivotal relation and a second cavity spaced from said elongated cavity; a third member pivotally connected with one of said first and second members and releasably mounted in the other of said first and second members, said third member including a first rounded head portion pivotally received in said cavity of said first member and a second rounded head portion releasably received in said cavity of said second member; and a sheet-like elastically yielding member mounted on a flat face of said first member.
2.
A valve as set forth in claim 1 which further comprises a member secured to said third member in perpendicular relation to define a handle for pivoting of said third member relative to said one member.
3.
A valve as set forth in claim 1 wherein said second member has a substantially U-shaped cross-section including a central web having holes for passage of a fastening means therethrough.
4.
A valve for an air duct in a window frame, said valve comprising a first member forming a valve body for closing off the air duct, said member including a rounded head portion at one end and a cavity spaced from said one end; a second member pivotally connected with said first member to define a holder, said second member including an elongated cavity receiving said head portion of said first in pivotal relation and a second cavity spaced from said elongated cavity; and a third member pivotally connected withh one of said first and second members and releaseably mounted in the other of said first and second members, said third member including a first rounded head portion pivotally received in said cavity of said first member and a second rounded head portion releaseably received in said cavity of said second member
