The chock comprises a pair of slidably engaged wedges which are adjustable between a large dimension and a small dimension upon relative sliding of the wedges, which are biased to a large dimension. The device may be inserted and provide a secure protection point in a narrow, smooth-walled, paralleled-sided crevice and is constructed to provide a point of attachment to which a safety line may be secured.
