Description

ABSTRACT OF THE DISCLOSURE The invention relates to a device for holding the edge of inner insulating mats which extends transversely to the longitud- inal direction of an air-conducting passage in the area of a frame-piecè of a prefabricated gland, where the metal frame- piece has a stay running inside the appropriate wall of the air- conducting passage and abutting the latte. A cross-conncetion is provided which, in the ready-assembled state, connects an inner stay of the frame-piece, resting on the outside of the wall, firmly to the latter. The inner stay is bent back on itself with multiple bends so as to form a pocket which is open in the longitudinal direction of the air-conducting passage and which has a catch strip extending transversely over the entire length of the pocket and pointing towards the inner stay. A plastic holding strip is provided, whose heat-conducting value is considerably below that of the metal of the frame-piece, and whose cross-section is large enough to hold the edge of the insulating mat. A part of the holding strip has a catch strip which is complementary to the catch strip of the pocket and which is flexibly inserted in the pocket.
