A coupler and a method for securing foam tube insulation elements to one another for pipes, comprising of a strip having a top surface and a bottom surface. The top surface may have a series of tab-like projections that define openings between the top surface and the bottom surface. The top surface may also have a series of teeth.

A coupler for to which a shaft is attachable is provided. includes a base. The base is formed with an upper side and an lower side. The lower side is substantially a flat planar surface. Means are provided for mounting the base on a curved surface. A preferred means is one or more ball washer assemblies. In addition, the present invention includes a tub that is adjustably connectable to the base. A plug is provided that is repositionably attachable to the tub. In addition, a neck is provided. Th...

A coupler having a tubular body (6) which is arranged to receive a tubular element for transporting fluid and including a pipe end, and which is provided with elements (11) for snap-fastening the tubular element, the coupler including a bushing (15) provided on the inside with elements (23, 25) for retaining the pipe end, which elements are selectively activatable and deactivatable, wherein the bushing is mounted in the tubular body to be movable axially between a position for activating the ret...

A female coupler comprises a valve support accommodated in a hole portion of the injection port and comprising a projecting portion having a axial hole, a cylindrical coupler main body placed around the projecting portion and comprising a locking projecting portion on an inner peripheral surface, a part of the main body being embedded in the injection port so as to have its position fixed, a base valve accommodated in the main body and having an fitting insertion portion inserted into the axial ...

The present invention provides a coupler having a high degree of coupling. The coupler comprises first and second dielectric substrates each having first and second surfaces which are parallel to each other. A ground conductor is formed on the first surface of the first dielectric substrate, and two coupling line conductors and are formed on the second surface of the second dielectric substrate close to each other so as to be electromagnetically coupled to each other. Via conductors and are fill...

A coupler (for joining tubing to a shoring leg or the like, having a T-shaped bolt slot extending along the length of such leg) is formed of a sickle-shaped metal strap or extrusion, having a C-shaped central portion, a radial extension portion at one end, and a tangential T-portion at the other end, said T-portion being formed of a head and a relatively narrow neck with adjacent opposing shoulders; and a T-bolt secured through a hole in the extension portion. The head and shoulders defining the...

A coupler for joining two objects comprises an insertion member attached fast to one of the objects and a reception member attached fast to the other object and used for admitting the insertion member into fast engagement therewith. The insertion member is provided with a setting portion for fast attachment to the aforementioned one object and a shaft extended from the setting portion and possessed of a radially expanded engaging portion at the leading end thereof. The reception member is provid...

An apparatus to connect two portions of at least one cable together comprising a male member, a female member and an actuation means. The actuation means is adapted to radially displace the first or second portions of the cables to engage each other. The actuation means typically comprises a tapered rod, and the male member is normally inserted into the female member and the rod is moved along its central axis so that engaging portions abutting against the rod move radially outwards causing the ...

A coupler comprising a female coupling member and a male coupling member adapted to be fitted therein for coupling air conduits of two systems, i.e., an air pressure supply system and a control system thereof, wherein the coupling members have openings of a first and a second air conduit, respectively, at respective central portions of the mating faces and annular grooves concentric with and outer than the respective openings; third and fourth air conduits open at the respective grooves; the ope...

An improved mechanical coupler which is utilized in systems for tapping kegs of fluids which are kept under pressure. The improvement consists of a probe head which is fixed relative to the probe of the coupler and a large flexible fluid seal which is designed in three sections such that the two uppermost sections enable the seal to fold in on itself while the lowermost section lies substantially flat against the valve assembly to thereby form a very secure sealing means between the probe and th...
