Abstract: Crimping tongs in particular for crimping a sleeve on a cable, said tongs having jaws coupled to each other so that one moves relatively to the other, a cam (15) driven by a ratchet wheel (16) which actuates a toggle joint device (20,21,22) a catch being installed on the moving handle (13) so as to drive the ratchet wheel step by step by moving the moving handle, the toggle joint device making the moving jaw (12) rotate in the closing direction. With a view to axial crimping, the moving jaw (12) has a moving die (14) which moves rectilinearly. A spring (25) biases the toggle joint to move the one jaw toward the other, and a trigger (19) is pressed to open the jaws sufficiently for insertion of a sleeve to be crimped. Releasing the trigger causes the jaws to hold the sleeve under the action of spring (25); so that the crimping action can be performed with one hand.
