The non-adhered edge (20) makes it possible not only to more easily take hold of and remove the tear strip, but also prevents a piece of the tear strip (2) from remaining on the profile member (1) and hindering the adhering of the profiled members to each other. The two edges (20, 21) of the tear strip (2) may be non-adhered, and, when the profile member (1) is covered by a tear strip (2) on each face, the two tear strips (2, 2') are each non-adhered on at least one side. The profile member can be either flat or circular.
