A tool for fixing a tension clamp including a pair of levers pivotable about parallel axes and carrying at their ends plier jaws that can be moved toward each other and act on the clamp. To monitor the forces occurring during the locking of a buckle and a clamping band of the tension clamp, use is made of a device that has a housing fixed with respect to the tool and power transmission arms. Each power transmission arm is at one end elastically articulated to the housing, has at the other end a contact surface for a force sensor (18) attached to the housing and has, between its ends, a bore, in which the axis of the relevant tool lever is supported. A force/time or force/path curve obtained from the sensor signals is used as a measure of the quality of the locking between the buckle and the clamping band.

A drainage pipe connection tool for connecting two adjacent sections of corrugated, high density polyethylene (HDPE) drainage pipe or a section of HDPE drainage pipe to a collecting basin includes a first brace member, a second brace member with a tensioning member pivotally fitted thereto and straps extending between the first brace member and the second brace member. In use, the first brace member is fitted to one of the corrugated sections of HDPE drainage pipe or behind a female bell-shaped opening of the basin, and the second brace member is fitted to the adjacent section of HDPE drainage pipe. The straps are pulled taut to remove slack, and a lever of the tensioning member is operated to apply tension on the straps, urging the adjacent drainage pipe sections together or the pipe section into the open female bell of the basin.

Technologies are described for devices and methods to couple a hose to another hose or apparatus. The device may comprise a first side with at least two barbed fittings, each configured to insert into a flexible hose to create a waterproof seal. A diameter of each barbed fitting may increase in size from a first end of the first side to a second end of the first side. The device may comprise a second side with at least two male fittings, each configured to threadly interact with threads of a female fitting to create a waterproof seal. A diameter of each two male fitting may increase in size from a first end of the second side to a second end of the second side. The device may comprise a separator rim attached to the second end of the first side and to the second end of the second side.

At least some aspects of the present disclosure feature a convective system including an inflatable convective device and a manifold. The inflatable convective device has a pneumatic structure and two openings into the pneumatic structure. The hose manifold includes a hose connector configured to connect to a hose, two outlet connectors configured to connect to the two openings respectively, where the hose connector and the two output connectors are in fluid connection.

A connector for a flexible non-metallic conduit is provided. The connector may include a gland nut for receiving the conduit, and a gland ring within the gland nut. The gland ring may be sized to extend around the conduit. The connector may further include a body threadably secured to the gland nut, and a ferrule disposed within the body, wherein the ferrule includes a first keying feature coupled to a second keying feature of the body to cause rotation therebetween, and wherein the ferrule is inserted partially into the conduit. In some embodiments, the gland nut is not directly physically coupled to the conduit, so the gland nut may slide over the conduit towards/away from the body. In some embodiments, during assembly, the body and the gland nut may be rotated together to cause external threading of the ferrule to engage an inner wall of the conduit.

An end-fitting and an unbonded flexible pipe, where the unbonded flexible pipe includes from the inside and out an internal pressure sheath, at least one armor layer and an outer sheath, the end-fitting further includes a sealing element. The sealing element includes a seal casing concentrically arranged around the internal pressure sheath, the seal casing includes a recess in which a first sealing element is concentrically arranged around the internal pressure sheath such that the surface of the first sealing element at least forms a line contact with the internal pressure sheath, and a second sealing element is concentrically arranged around the internal pressure sheath in the recess such that the surface of the second sealing element at least form a line contact with the surface of the seal casing and form a line contact with the surface of the first sealing element.

A hose connector has: a cap, a connecting pipe and an assembly pipe. The cap has an inner ring and an outer ring, and the inner ring is provided with an inner threaded hole. The cap further has a socket hole connected with the inner threaded hole, the outer ring is provided with an outer threaded section. The connecting pipe has an inserting portion at one end and a first threaded portion at another end. The inserting portion has a neck section and a stopping ring. The inserting portion is disposed in the socket hole of the cap. The stopping ring comprises at least one protrusion facing the groove. The assembly pipe has a through hole and a convex ring at one end and a second threaded portion at another end. The second threaded portion of the assembly pipe engages with the inner threaded hole of the cap.

A hose connector has a first connecting joint, a second connecting joint, and a connecting duct. The first connecting joint comprises an inner neck rim having an inner threaded aperture and a containment space connecting to the inner threaded aperture. The first connecting joint further comprises a threaded outer wall, and a bottom surface of the neck rim has a plurality of engaging grooves. The second connecting joint comprises a hollow base having a neck section connected to a lip, and the neck section is configured for insertion in the containment space of the first connecting joint. A top surface of the lip has a plurality of engaging protrusions pushing against the neck rim or engaging with the engaging groove. The connecting duct comprises an outer threaded section and an enlarged flange, and the connecting duct is mounted through the neck section and the lip.
