Abstract
Redetachable, self-adhesive hook or similar fixing device, characterized by a strip (1) of an adhesive film for reseparable bonding based on a thermoplastic rubber and tackifying resins, wherein the adhesive film has high elasticity and low plasticity and wherein the adhesion is lower than the cohesion, the adhesive power largely disappears on extension of the film, the ratio of the peel strength to the tear load is at least 1:1.5, and wherein an adhesive bond produced with this can be separated by pulling on the adhesive film in the direction of the adhesion plane, wherein one end of the strip (1) is provided on both sides with a covering (4), which at the same time serves as a tab for pulling, wherein at least the covering (4) located on the front side is opaque to UV and wherein the front side of the strip (1) carries, except for in the region of the covering (4), a baseplate (3) having a peg-shaped extension (2) pointing forwards, and the reverse of the strip (1) is covered with a release paper or a release film (5) which has a tab (6) in the region of the covering (4).
