The present invention relates to an end plug (1) to be inserted axially into the centre of an end of a paper roll, and provided with a holding element (3) adapted hold and /or guide said end of said paper roll in correct position in a dispenser, said holding element being movable between a transport position, in which the whole of the holding element is accommodated within the interior of an outer sleeve (2) of the end plug, and an active position, in which a part of the holding element protrudes outwardly from an outer end of the outer sleeve, the outer sleeve includes a conical wall (8), the base end of which defines the outer axial end of the outer sleeve, the holding element includes two opposite slide elements (6,7) guided in diametrically opposite spoke elements (11,12) projecting inwards in a radial direction in relation to the inner wall of the conical wall of the outer sleeve. According to the invention the outer sleeve (2) has such a shape that reaction forces acting on the outer sleeve when it is inserted into the centre of an end of a paper roll are larger in at least two opposite regions thereof lacking inwardly projecting spoke elements (11,12) than in regions from which spoke elements project inwards. |
