Abstract
Abstract A net comprising mutually crossing lines intersected at the intersections to form meshes by two-piece thermoplastic connectors, the parts of which are ultrasonically fused together in situ. The two parts of each connector have grooves and recesses that match to define holes that receive and capture segments of the lines adjacent the intersections and a cavity that receives and captures the segments of the lines at the crossing points.
