ABSTRACT A riveting tool (10) of the kind comprising an elongate, headed, mandrel (22) on which a plurality of tubular rivets are supported as a column, and which can be gripped and reciprocated relative to an abutment (20) by reciprocable gripping jaws (26) so as to draw the head of the mandrel (22) through each rivet supported in turn by the abutment (20), and having means (24) for feeding the column of rivets towards the head of the mandrel (22), has both the rivet feeding means and the gripping of the mandrel by the jaws (26) operated pneumatically, each respectively being under the control of a manually operable valve (68,82). In order to avoid the possibility of the feeding means (24) being actuated at a time when the mandrel (22) is not gripped by the jaws,(26) the valves are interengaged with a detent (132) arranged to prevent opening of the valve (68) which controls the rivet feed means (24) when the valve (82) which controls the jaws (263 is closed.
