Abstract: A modular grid comprises a faceplate having at least one front opening and at least two tabs on its periphery, a sleeve configured to abut on the faceplate, and at least two attachments, each attachment being configured for insertion into an opening formed in a corresponding one of the at least two tabs and into a corresponding opening formed on the perimeter of the sleeve. The modular grid may be mounted on an extremity of a conduit, whether at its inlet or outlet side, and be shaped for mating with the extremity of the conduit. A perimeter of the faceplate may be circular, square, oval, rectangular, triangular, pentagonal, hexagonal, or octagonal.

Abstract: A connector for connecting lengths of conduit sections having an outer corrugated surface, comprising a body having apertures, an outer rigid surface and an inner deformable surface as well as opposite open extremities. The inner surface defines a channel for receiving at least one conduit section through at least one of the open extremities. Fasteners are inserted into the channel through said apertures. When the corrugated conduit is fitted into the channel, the fasteners are insertable through the apertures for extending into the channel thereby interfering with the corrugated surface of the conduit and substantially preventing the conduit from being removed from the channel.

Abstract: The present invention relates to connectors and more specifically to a connector for drainage conduits that are typically used for carrying liquid or semi-solid matters from one location to another. The connector includes a body provided with a passage, apertures and clips, the clips being so configured and sized as to be insertable to and removable from the connector such that the drainage conduits may be securely assembled to and disassembled from the connector. In an embodiment, the connector of the present invention further comprises a gasket for sealingly engaging drainage conduit sections.

Abstract: The present invention relates to a corrugated conduit with reinforcement and flow control features. The corrugated conduit includes an outer surface defining successive and alternating annular peaks and valleys, an inner surface defining successive and alternating annular peaks and valleys, and at least one band positioned along the circumference of the inner surface. When the corrugated conduit has a number of longitudinal, arcuate reinforcing bands, these may be identical or different in width and thickness, and they may be positioned evenly or unevenly apart, depending on the application. As an added measure to control fluid flow, the reinforcing bands may have a contact surface with turbulating texture that causes turbulence when in contact with a fluid.

Abstract: The present invention relates to a staple for holding a tubular member within a corrugated conduit, wherein the tubular member comprises an outer surface, and the corrugated conduit comprises an open end and an inner surface with successive and alternating annular peaks and valleys. The staple comprises a mechanically compliant convex wall slanted in a direction opposite to a direction of insertion of the tubular member in the corrugated conduit through the open end of this corrugated conduit.
