Summary:A camming device comprises a head (10) on which is carried a plurality of pivotable cam elements (28). Each cam element (28) can pivot between an extended position and a withdrawn position. A trigger (34) is operable to pivot the cam elements (28) towards the withdrawn position. A stem (12) is connected to the head (10), the stem having a first and a second portion, an end part of the first portion being secured to the head (10), and the second portion having two branches that are secured to a common termination component (50) at spaced-apart locations. The first portion of the stem (12) comprises a single tensile member (40) or a plurality of tensile members that extend in contact with one another. At least one cam element (28) has a body on which is formed a working surface (66), in which the body, as manufactured, has applied to it a coating, other than in the region of the working surface.
