Summary:A camming device comprises a head 10 on which is carried a plurality of pivotable cam elements 28. Each cam element can pivot between an extended position and a withdrawn position. A trigger 34 is operable to pivot the cam elements towards the withdrawn position. A stem 12 is connected to the head, the stem having a first and a second portion, an end part of the first portion being secured to the head, 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 may comprise a single tensile member 40 or a plurality of tensile members that extend in contact with one another. At least one cam element may have a body on which is formed a working surface (66, figure 4), in which the body, as manufactured, has applied to it a coating, other than in the region of the working surface.
