Abstract

Gripping block with a rear side, a front side and two opposing side faces, the rear side being adapted for abutment against an inner wall in a slot in a holding device, the front side being arranged with friction generating means over at least part of its outer surface, wherein a largest width of the rear side is shorter than a smallest width of the front side of the gripping block. The invention also relates to a holding device for a gripping block, and a method for replacement of a gripping block from a holding device.
