A bandage securing device comprises a first sheet part and a second sheet part, and optionally also a third sheet part. The first and second sheet parts are connected to each other along a connection line extending in a width direction and arranged to overlap each other, thereby forming a jaw-like structure in a longitudinal direction. At least one of said first and second sheet parts, and possibly both, are provided with at least one first adherent fastening layer on an internal surface facing said overlap. Further, the bandage securing device comprises at least one second adherent fastening layer on an external surface, not facing said overlap, to detachably connect to the bandage. This second adherent fastening layer may be provided on one of the first and second sheet parts, and/or on the third sheet part.
