Zusammenfassung:	1. Linkage for operating and/or connecting flap-type valves of a heating, ventilating or air conditioning system, the ends of which are constructed for connection to a first and a second lever (8, 11), which are secured to the flap-type valves (6, 7), whereby the linkage can be adjusted over its length and includes an arm (19) as well as an operating rod (16), which is held at one end in relation to the longitudinal axis at a second lever (11) so that it cannot be rotated and is provided at least in one section with an external thread (17) which is disposed in an internal thread of the arm (19) acting at a first lever (8), whereby the arm (19) acting at the first lever (8) includes a nut (18) containing the internal thread (40) which is rotatably mounted for the purpose of the adjustment in relation to the operating rod (16) and the arm (19) and the arm (19) acting at the first lever (8) is provided with a substantially cylindrical space (30) which is formed between two shell-type parts (24, 28) which can be brought into engagement with each other, whereby the shell-type parts (24, 28) are connected by means of a film hinge (29) and a clamping or click-stop connection (33, 41) is formed for the nut (18) by the shell-type parts (24, 28), by means of which the nut (18) after the adjustment is fixed in its position in relation to the arm (19) and the operating rod (16).
