Provided is a corrugated pipe connection device. The device includes a corrugated pipe including a groove and a ridge that are successively and alternately formed, a nut into which one side portion of the corrugated pipe is inserted, wherein the nut has a screw-thread on an inner circumferential surface thereof, a clamping ring being formed in a ring shape cut at one place thereof and including an inner portion formed convexly in a radially inward direction of the corrugated pipe to be inserted into the groove of the corrugated pipe and an outer portion protruded in a radially outward direction from the inner portion, wherein the outer portion comprises an outer circumferential surface, and a socket having a screw-thread on an outer circumferential surface thereon onto which the nut is screwed.

A connector assembly (608) for a length of corrugated tubing (601) having an inner corrugated element (602) and an outer flexible sheath layer (603). The connector assembly (608) comprises a fitting (609) including a fluid-flow passage and an abutment surface (612) for the corrugated tubing (601) to seat thereon; axial loading means operably connectable to the fitting (609), the axial loading means including a connector (613) and a collet (610), the collet (610) having a radially inward protruding clamping element (611) for insertion into a trough (606) of the inner corrugated element (602), and a sheath-contact portion (625) for engaging the outer sheath layer (603), so that, when the connector (613) moves the collet (610) into engagement with the fitting (609), the collet (610) causes the corrugated element (602) to move onto the abutment surface (612) whilst maintaining engagement with the outer sheath layer (603). The sheath-contact portion (625) is axially positionable between the inner corrugated element (602) and the outer sheath layer (603) of the corrugated tubing (601), in use.

A hose assembly includes an inner core tube, a connector including a stem portion inserted into a distal end of the inner core tube, an outer metal tube substantially coaxial with and surrounding the inner core tube, and a collar substantially coaxial with and surrounding the distal end of the inner core tube. The outer metal tube terminates at a distal end axially inward of the distal end of the inner core tube. The collar includes a flared first end welded to the distal end of the outer metal tube and a second end welded to the connector.

A coupler assembly kit and methods of use are described. Embodiments of the coupler assembly kit can be implemented to couple a corrugated pipe to a concrete section. Generally, the assembly kit can be implemented to couple a spigot end of the corrugated pipe to a bell end of the concrete section. In one embodiment, the coupler assembly kit can include a circumferential cable, a plurality of second cables having a threaded rod on end and an eye bolt on the other end, a plurality of linkage crosses, and a gasket. The coupler assembly kit can be assembled and implemented on location to connect a high-density polyethylene corrugated pipe to a reinforced-concrete flared end section.
