Abstract of the Disclosure A bidirectional line clamp for a pole climbing aid to be used by linemen has a rigid housing providing means of attachment to an external anchoring means, the housing having opposed front and rear walls and a peri- peheral side wall defining therewith an elongated opening. The side wall provides a pair of opposed gripping sur- face portions terminating at the opening. A clamp member is pivotally mounted in the housing for pivotal movement about an axis perpendicular to the front and rear walls between first and second operative positions, the clamp member defining with the peripheral side wall an opening for a line to be clamped. The clamp member has an edge portion providing a second gripping surface co-operable with one or the other of the first gripping surface portions for clamping the line against it to prevent movement of the line in one direction only. The clamp member is pivotally movable between the first and second operative positions in response to traction exerted on the line, for clamping the line in a required position.
