1. A bone anchor comprising:
a main body defining a longitudinal axis and comprising a head and at least one insertion hole, which extends from a first opening formed in the head to a second opening formed in the main body, the at least one insertion hole having an axis which is arranged to be inclined with respect to the longitudinal axis of the main body at an angle, and wherein the insertion hole is configured to receive and guide therethrough a pin-shaped element to be anchored within a bone or a bone fragment; and a locking device attachable to the main body to fix a position of the pin-shaped element in an axial direction when the pin-shaped element is received within the insertion hole, the locking device comprising a recess and a projection extending in the recess along the longitudinal axis when the locking device is attached to the main body, the projection comprising a surface, wherein the axis of the insertion hole extends toward the surface when the locking device is attached to the main body, such that the surface is configured to contact a portion of the pin-shaped element protruding from the first opening when the pin-shaped element is received within the insertion hole.
