Abstract
A metal sleeve including a metal body which surrounds an inner channel running between a proximal and a distal opening. The inner channel has at least one groove set back into the metal body, running in the longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge. The proximal front edge of the groove is produced by impact extrusion.
