Abstract: Pliers for positioning clips which form connecting rings between a wire netting and support wires. The pliers comprise two arms pivotally connected together, with the front ends of these two arms causing displacement of two small rods articulated on a same pin which is rigid with a mobile part guided between two plates which form a body for the pliers and carry at a rear portion the pivot axis of the arms. The plates are spaced apart at the front end by a fixed part of substantially the same thickness as that of the mobile part, and each plate comprises an upper portion with an opening which, in cooperation with a clip supply magazine mounted perpendicularly to the plates, enables introduction of a clip behind the mobile part and deformation of the clip between the mobile part and the fixed part so as to surround the support wire and a wire forming the netting. Displacement of the pin which drives the mobile part is limited by openings provided in the plates which form the pliers body.
