An adhesive tape (20) having a carrier material (22) which is coated on the upper side with a self-adhesive compound (21) and is finished on the opposite underside of the carrier material with a cleavable system (23, 24) which, in turn, is finished on its underside with a further self-adhesive compound (25), in order to release a connection of mutually overlapping materials bonded over each other, in particular for producing a splice connection between two flat web materials wound up into reels during a flying reel change, is formed in such a way that the cleavable system (23, 24) cleaves as far as the overlap and, at the point of the overlap of the two materials bonded over each other, part of the cleavable system (24) and also the self-adhesive compound (25) located underneath tear off, so that the residue (24a) of the cleavable system ,(23, 24) that remains on the overlapped part (12) covers the remaining self-adhesive compound (25a) in a non-adhesive manner.
