The disclosure relates to an anchoring device adapted to hold one end of a to-be-stressed linear member within the bore hole of an earth formation. The anchor device has a tubular body surrounding and retaining a section of the linear member and has a compression channel extending along the circumferential portion of the body. The compression channel being open to the outside of the tubular body through a substantial part of its intermediate length to form a distribution channel.
