The hollow body is made up of a bottom section and a cover having a closable aperture. The cover is in clamping engagement with the bottom section. The bottom section has an annular wall laterally enclosing the hollow interior of the body. The height of the wall is less than the diameter of the circle. The bottom section has a floor which supports the wall and has a portion extending laterally beyond the wall. The floor also has an outwardly bulging obverse surface. The aforementioned laterally extending portion, and particularly an annular ridge formed thereon, supports the impact protection element. The minimum distance between an exterior point on the protective element and the obverse surface of the floor is no greater than 3 mm.
