Fixing system for mounting and dismounting a bending tool

A fixing system for fixing a bending tool, said tool having two fixing surfaces for fixing by clamping, and a retaining groove situated beneath one of the fixing surfaces, the groove presenting a top edge and a bottom edge, said system comprising:

• a clamping body having a first clamping surface suitable for co-operating with one of the fixing surfaces of the tool,
• a pivotally-mounted tool clamp having a second clamping surface, said clamp being capable of taking up a tool-clamping first position in which said fixing surfaces of the tool are clamped between said first and second clamping surfaces, and a tool mounting and/or dismounting second position in which said second clamping surface of the clamp is spaced apart from said first clamping surface of the body;
• and
• a tool-retaining member comprising a plurality of blades, each blade comprising:
• a first elastically-deformable branch secured in part to the clamp;
• a second elastically-deformable branch directed upwards and having an end suitable for penetrating into said retaining groove, and a portion suitable for co-operating with the bottom edge of said retaining groove when the tool pivots;
• and
• at least one angled portion located between said first and second elastically-deformable branches.
