Abstract: The invention relates to a device for picking up litter, in particular animal excrement. It comprises both a set of tongs having two arm-forming assemblies that are hinged to each other at their ends about an axis, each arm-forming assembly being extended beyond the axis by a control extension, a second end of each arm-forming assembly including a terminal portion, actuating the control extensions causing the terminal portions to move apart, and a bag having a bottom-forming portion disposed between the arm-forming portions, the remainder of the bag being folded around the terminal portions, the folded portion clinging to the terminal portions and/or the arm-forming assemblies.
