A rope clamping device which when attached to a rope R automatically clamps onto the rope R when drawn in one direction but slides along the rope R when drawn in the opposite direction, having means (pin A) for manually overriding the automatic clamping action, the clamping resulting from the rope being gripped between a rotatable sprung pivot tooth T(i.e., the tooth T which is pivoted (at O) and biased by spring E towards the rope) and a static pressure plate P both contained within a rigid enveloping body D. The pivotal action causes the tooth T to progressively indent into the rope's cross-section wherein the profile of the tooth (which may be concave) presented to the rope is advantageous to the initiation and development of clamping without damaging the rope. Preferably there exists a plurality of said teeth T, serially spaced and caused to move in unison by an interconnecting member J. |
