An assembly for connecting a line includes a connector for detachable connection of a line, a line that can be connected to the connector, and an intermediate element for connection to the connector and the line. The intermediate element is secured on the line in such a manner that it separates the line and the connector from one another.

One variation may include a telescoping pipe comprising: a first pipe and a second pipe, wherein the second pipe is constructed and arranged to stretch and retract along the first pipe so that a length of the telescoping pipe can be extended or shortened; a first O-ring coupled between the first pipe and the second pipe; and a second O-ring coupled to an inner surface of the second pipe.

The invention concerns a coupling for use in forming a sealed joint between first and second tubular members. The coupling provides a through-passage defined by an inner coupling face and having a first open end for insertion of the first tubular member into a first region of the through-passage and a second open end for insertion of the second tubular member into a second region of the through-passage. A first inwardly directed engagement recess is provided in the inner coupling face in the first region of the through-passage and a second inwardly directed engagement recess is provided in the inner coupling face in the second region of the passage. In the assembled joint, the first inwardly directed engagement recess aligns with a first outwardly directed engagement recess of the first tubular member to form a first channel for receipt of a first retainer to secure the first tubular member in the coupling. The second inwardly directed recess aligns with a second outwardly directed engagement recess of the second tubular member to form a second channel for receipt of a second retainer to secure the second tubular member in the coupling. The first region of the through-passage has a larger diameter than the second region of the through-passage.

Example aspects of a gasket bridge for an end ring assembly and a method for using an end ring assembly are disclosed. The gasket bridge can comprise an arcuate body defining an inner surface, an outer surface, a first bridge end, and a second bridge end, the arcuate body defining a bridge radius of curvature; a first ramp extending from the first bridge end; a second ramp extending from the second bridge end; and a projection extending from the inner surface.

A clamping arrangement includes a clamp member and an elastomeric member. The clamp member is operative in a first orientation having a first inner diameter and a second orientation having a second inner diameter. The first diameter is greater than the second diameter. The elastomeric retaining member is carried by the clamp member and is operative to temporarily retain the clamping arrangement to a first tubular member having an outer diameter less than the first inner diameter when the clamp member is in the first orientation.

A locking pipe joint device employs a center body connector, one or more sealing elements, such as a wiper seal and a sealing ring, a sealing ring retainer, an indicator ring and a retaining cap. In various embodiments, the retaining cap and the center body connector include mating block members that permit sliding bolted connection along an axis perpendicular to the main axis of the center body connector, which allows the retaining cap to tighten the packing arrangement components around an inserted piping or tubing element, and in secure engagement with the interior of the center body connector.
