ABSTRACT:
The end piece for a roll of wiping material comprises a cylindrical bearing surface tightly fitted into a core that supports the roll, a transverse flange that protrudes from the cylindrical bearing surface and rests against an opposite-facing surface of the core and the roll, and an axially extending neck that has a head with an internal hole and a hollowed-out section forming a guide groove. The hollowed-out section is located between the head and the cylindrical bearing surface. The head and part of the hollowed-out section are deformable and internally provided with a hole that creates deliberate fragility facilitating, by crushing, their deformation as the core and the end piece are extracted from an accommodating side plate. After the core and end piece have been extracted, the head of the end piece is, in its final state, permanently deformed and cannot be reused.
