In another embodiment, a connector includes two different attachments and the connector can be affixed to a flexible duct end. In another embodiment, a method includes providing a flexible duct with different attachments at one end of the flexible duct, and flowing air through the flexible duct. In a further embodiment, a method includes providing a connector having two different attachments.

A connecting assembly (10) for connecting to a corrugated tube (12) includes a base body (14) with a receptacle recess (14a) for receiving the corrugated tube (12), and a latching unit (16) which can be introduced through a circumferential opening (14c) of the base body (14) into the receptacle recess (14a) and which has a latching element carrier (20) and a plurality of latching elements (22) constructed as one piece with the latching element carrier (20). The latching elements (22) are constructed for the purpose of engaging in a trough (12b) of the corrugated tube (12) and to resist a movement of the corrugated tube (12) out of the receptacle. The latching element carrier (20) is constructed as a split ring. The latching elements (22) are arranged uniformly distributed along the circumference of the latching element carrier (20).

A sewer hose including a corrugated central body integrally joined at opposing longitudinal ends by attachment collars, a first collar defining one or more locking channels, and a second collar defining one or more lugs sized and shaped for insertion into respective channels. A method of manufacturing the hose is also disclosed, including the steps of providing mold segments sized and shaped to produce the aforementioned collar sections as well as the corrugated central body, deploying them in a molding apparatus, and injecting a polymeric material into the mold segments so as to form a sewer hose with integrally attached male and female attachment collars, negating inefficient and ineffective attachment adapters.

A connecting union joint with smart connection of an easy-flowing pipe system includes a joint body, wherein an end of the joint body is provided with a pipe connecting device which includes a sliding base, a snapping tooth piece, a reset spring, a spring pad and a snapping ring. The joint body is internally provided with a snap slot. The reset spring is arranged between the spring pad and the sliding base. The sliding base is evenly provided with a plurality of through openings. tooth The snapping tooth of the snapping tooth piece deeply extend into an inner wall of the sliding base and are snapped with an outer peripheral surface of the pipe. An inner wall of the joint body is provided with a moving area for allowing the snapping tooth piece to move therein.

A connection device for connecting a suction tube to a machine tool includes a tube piece which has a machine tool-side inlet opening, a suction-side outlet opening, and a tube curvature disposed between the inlet opening and the outlet opening. The tube piece has a guiding section disposed between the tube curvature and the suction-side outlet opening where a free end of the suction tube is receivable in the guiding section such that the free end is guided linearly within the guiding section. The connection device also has an end piece arrangeable at the free end of the suction tube and an adapter counter piece arrangeable on the suction tube at a distance from the end piece. The end piece is disposed completely within a volume defined by the guiding section and the adapter counter piece is disposed at least partly within the volume.

The invention relates to a connection assembly (1) for a fluid system, in particular for a coolant system, comprising a line, in particular a coolant line (2), and a connection element (3), wherein the line (2) is designed as a corrugated tube (4) with a corrugated structure (5), wherein the corrugated structure (5) extends up to at least one end (9) of the line (2), wherein the end (8) of the corrugated tube (2) is connected to a connecting piece (11) of the connection element (3), wherein the connecting piece (11) has an outer contour (12) in the shape of a pine tree, onto which the end (8) of the line (2) is pushed on using a plug-in length (10). According to the invention, the corrugated structure (5) on the end of the line is compressed across the push-in length (10). The invention also relates to a method for producing a connection assembly for a fluid system.

A pipe connector comprises a circular flange having a central opening. A downstream sleeve having a circular cylindrical form about an axis with a proximal end and a terminal distal end, is attached to the circular flange by the proximal end and comprises at least one first type of detent and at least one second type of detent.

A securing device is disclosed having a flange mountable on a suction-providing source, and having pipe members that detachably receive a corrugated pipe such as a drain tile. A major or outer pipe is concentrically and integrally joined to, and extends perpendicularly from the flange. The outer pipe includes a rod receiving slot extending circumferentially and radially through a predetermined portion of the outer pipe. A minor or inner pipe is concentrically and integrally joined to, and extends perpendicularly from the flange such that the inner pipe is concentrically disposed inside the outer pipe. A latch is mounted on the outer pipe and is and is movable between a latched position and a fully unlatched position. A securing rod is pivotally connected to the outer pipe and is operatively associated with the latch subassembly so as to be movable from a secured position to a released position. When the latch subassembly is in the fully unlatched position, the rod is in the released position, and when the latch subassembly is in the latched position, the rod is in the secured position to detachably secure the position of a drain tile upon the inner pipe.

Disclosed is a system comprising a body having a first mating surface, a first piping extending through the body and having a second mating surface facing the first mating surface, a retaining collar around the body, a second piping having an end between the retaining collar and the body, and at least one seal between the first piping and the second piping to create a watertight seal.
