A compression collar is manufactured for use in reinforcing an interference fit between an end of a pipe and a fitting. A precursor form is injection molded using a cold-expansion material. The precursor form has a tubular body with an initially closed axial end and a bore that is initially blind formed in the other axial end. Material is removed from the initially closed axial end of the tubular body of the precursor form to form an opening in the initially closed axial end that connects to the bore thereby forming the compression collar. The opening has an inner periphery with a profile in axial cross section that is different than any profile in axial cross section of an inner periphery of the bore. The collar formed may lack knitlines and may include tabs formed during the removal step which help to position the collar on a pipe.

A hose clamp developed for hose structures used in many fields particularly in the automotive sector. The hose clamp includes a clamp band which surrounds the hose, a clamp housing which engages both ends of said clamp band, at least one positioner clip which limits radial and axial motion of the hose clamp on the hose, a wing with springy feature which is located on the positioner clip and allows diameter reduction of the hose clamp, a structure which couples the positioner clip to the hose by a plurality of serrations and does damage the hose.

A garden hose has an inner tube for conveying water at domestic water pressure from a first coupler disposed at a first end of the inner tube to a second coupler disposed at a second end of the inner tube, the inner tube being waterproof and flexible, the first coupler adapted to threadedly connect to a conventional water faucet and the second coupler adapted to threadedly connect to a conventional garden appliance. The hose has a metal sheath disposed over the inner tube and extending from the first coupler to the second coupler, the flexible metal sheath having a first shoulder near the first coupler and a second shoulder near the second coupler, the metal sheath being flexible, and a fabric sheath disposed over the metal sheath and fixed to the metal sheath by a first constricting band disposed at the first shoulder and a second constricting band disposed at the second shoulder.

A retaining apparatus includes a barrier having an interior surface defining an aperture extending from a first end of the barrier to a second end of the barrier. The retaining apparatus has a first distance between opposing sides of the interior surface near the first end of the barrier, a second distance between the opposing sides of the interior surface at a position between the first and second ends of the barrier, and a third distance between the opposing sides of the interior surface at the second end of the barrier. The second distance is smaller than the first and third distances. The interior surface is configured to partially surround and support a work line, restricting movement of the work line in a transverse direction, allowing movement of the work line in a longitudinal direction, and allowing bending of the work line about an axis in the transverse direction.

A hose construction having a coupling secured to an end of a hose, with the coupling including a tubular insert formed with a polymer mixed with chopped reinforcement fiber and including first and second ends, with the first end being inserted in the hose, and the second end including a connector interface. A tubular metallic ferrule is connected to the tubular insert adjacent to the second end in order to form an annular hose receiving space between an outer surface of the insert and an inner surface of the ferrule. The end of the hose is received in the annular hose receiving space, and the ferrule is deformed inwardly against the hose to form a secure connection. The tubular insert formed of a non-metallic material has high strength and is resistant to corrosion due to contact with the materials being transported.

A method for coupling a tube to a tube fitting includes radially outwardly expanding a tubular compression collar from a constricted state to an expanded state, the compression collar having a throughway extending there through and being made of a resiliently flexible material. An end of the tube is inserted within the throughway of the expanded compression collar, the tube bounding a passage. A tube fitting is inserted within the passage of the tube. The compression collar is allowed to resiliently rebound back towards the constricted state so that the compression collar pushes the tube against the tube fitting.

A fitting for connecting pipes, in particular flexible pipes, includes a first tubular element, provided with a first inlet/outlet opening and at its interior defining a first duct, and a second tubular element, provided with a second inlet/outlet opening and at its interior defining a second duct. The two tubular elements are connected together in a manner such that the first and second ducts are in communication. The first tubular element is provided with at least one through opening, between an external surface thereof facing outwards and an internal surface directed towards the first duct. The through opening defines a respective empty space between the external surface and the internal surface of the first tubular element. The fitting operates in an insertion condition, in which it allows a pipe to be fitted around said first tubular element, and a clamping condition, in which the pipe is pressed and stably locked on the first tubular element. In the clamping condition, the empty space defined by the through opening is occupied by a portion of the pipe pressed on the first tubular element.

A tubing junction assembly may include a body, and a collar coupled to the body. The body may include a head portion, a base portion, and an intermediate portion. At least a portion of an outer surface of the body at the intermediate portion may define a cross-sectional width that tapers from the head portion to the base portion. The collar may have an inner surface defining a passage. A tubing may be stretched over the outer surface of the body with a proximal end portion of the tubing stretched over at least a portion of the outer surface of the body at the intermediate portion. The inner surface of the collar may be sleeved over a portion of the outer surface of the tubing and coupled to the collar such that the proximal end portion of the tubing is sandwiched and compressed between the body and the collar.

Tubing retention systems are described herein. A tubing retention system includes a spigot, a tubing, and a collar. The spigot includes a spigot body and a spigot extension extending from the spigot body, wherein the spigot extension comprises a flared portion opposite to the spigot body and the spigot body and the spigot extension cooperatively define a spigot lumen. The tubing includes an outer surface and a tubing lumen, wherein a coupling portion of the tubing is disposed around the spigot extension, permitting fluid communication between the tubing lumen and the spigot lumen. The collar is disposed radially around the outer surface of the tubing and axially between the flared portion and the spigot body, wherein the collar radially engages the coupling portion of the tubing disposed around the spigot extension to axially and radially retain the tubing with the spigot.
