A wire-laying tool has a central passageway terminating in a probe which can be retracted relative to a stem against the force of a spring by means of a piston movable in a chamber. A spring-loaded pawl is actuated by another piston movable in a chamber. The pawl can advance the wire in the passageway and probe forwardly of the front end of the tool. When the piston has almost completed its stroke, fluid pressure is communicated to the chamber to cause retraction of the probe. A spring-loaded dog acts as a brake for wire in the passageway. The tool is intended for use in the production of wiring harnesses with the aid of a robot manipulator.
