A seal for gas channels of a regenerative heat-exchanger with respect to the interior space of the housing surrounding gas channels and a storage body, which consists of a sealing bar that abuts with a slide layer at the storage body and of a sealing diaphragm which is supported at a support member provided with covered off notches and which extends obliquely over the gap between the sealing bar and the oppositely disposed housing wall and abuts at the housing wall with its upper edge projecting beyond the sealing bar; the support member thereby forms an acute angle in cross section whose one leg abuts flat at the sealing bar and is secured thereat only within the area of its edge opposite the angle apex, whereas a sealing diaphragm is secured to the other obliquely extending leg at the inside within the area of the angle apex which is assembled of individual sealing lamellae that mutually overlap between two notches of the support member and that, within the area of their overlap, are pressed against the support member by angularly bent leaf springs.
