A connecting system is provided for detachably connecting a first pipe end to a second pipe end. The first pipe end has a sealing cone facing toward the second pipe end and a shoulder section. The connecting system includes a first clamping disk surrounding the first pipe end and a second clamping disk surrounding and connected to the second pipe end. The connecting system further includes a multiplicity of screws, detachably connecting the first clamping disk to the second clamping disk. The first clamping disk includes an outer circular disk ring and an inner circular disk ring which is detachably connected to the outer circular disk ring. The inner circular disk ring has multiple separate circular disk ring parts, and an outer diameter of the inner circular disk ring is greater than an outside diameter of the shoulder section provided on the first pipe end.

A composite pipe termination is provided comprising: a) a composite pipe having an interior pipe surface, an exterior pipe surface, a pipe end and a liner; b) a composite annular portion attached to the exterior pipe surface, the external surface of the annular portion comprising circumferentially extending ridges; c) a collet having an interior collet surface, wherein the collet encloses at least a part of the annular portion and wherein the interior collet surface comprises circumferentially extending grooves, and wherein circumferentially extending ridges on the external surface of the annular portion mesh with circumferentially extending grooves on the interior collet surface to provide axial movement blocking means; d) an annular collar which encloses and mates with the collet to prevent the collet from moving axially relative to the annular collar; e) an end-fitting locked to the annular collar.

A hose includes a tubular section having an outer tube and an inner tube. The inner tube forms a liner for the outer tube. Apart from being connected by connecting means near both ends of the tubular section, the inner tube is unconnected to said outer tube.

A connection element for connecting lines for conducting a fluid, in particular of a fluid circuit of an air-conditioning system of a motor vehicle, is based on the object of specifying a connection element which has high rigidity and low weight and which allows a fluid-tight connection with low production costs. This object is achieved in that the connection element has an attachment means and a connection means, wherein the connection means is arranged in a recess in the attachment means.

A method is described for fastening coupling means to respective ends (25,26) of pipes (10, 12) that are to be joined together, comprising a pair of mutually axially telescopic conical casings (18,22) that are inserted, one on each pipe end, as the conical casing pair are mutually pushed together with the help of respective tightening bodies (14, 16) so that the radially outer casing (18) squeezes the inner casing (22) into a fastening against the surface of the pipe (10, 12) and joins the pipe ends together, so that a tight joining together is achieved between the ends (25,26) of the pipes (10, 12) and it is characterised in that an inner conical casing (22) is used which is divided into a number of sections of axially directed slits (30) through the wall of the casing, said slits (30) contribute to the inner casing being able to be forced radially inwards during the simultaneous closing of the slits (30) and so that the inside of the inner conical casing is forced into a fastening against the surface of the pipe during the mutual pushing together of the casings. A coupling construction and an application of this are also described.

A cut-in fitting has a flange hub, a flange ring, a central body, a first gasket, a second gasket, a split flange hub, a split flange ring and a band clamp.

A pipe connection fitting is disclosed in the present application. The pipe connection fitting includes a gasket holder ring, a flap ring and a grip ring operably coupled together. A terminal housing is configured to engage with the gasket holder, flap ring and grip ring to form the pipe connection fitting adjacent an end of a pipe. The flap ring includes a plurality of tabs extending therefrom to provide an abutment for controlling a relative position of the grip ring.

A sensor assembly (5) for a fluid meter (100) is provided. The sensor assembly (5) comprises a sensor assembly body (6) and one or more circumferential grooves (303) formed in the sensor assembly body (6). Two or more retaining components (105, 106) are removably coupled together around at least one of the one or more circumferential grooves (303) with a portion of the two or more retaining components engaging the circumferential groove. A flange (104) is also provided that surrounds at least a portion of the sensor assembly body (6) and is retained around the sensor assembly body (6) by the first and second retaining components (105, 106).

A flexible tube assembly includes a metal tube having large diameter portions and small diameter portions positioned alternately along a longitudinal axis of the metal tube; a wire braiding mounted around the metal tube; a first ring fitted in one of the small diameter portions of the metal tube; a second ring positioned to secure the wire braiding around the first ring; a first annular member and a second annular member positioned on opposite sides of the first ring and the second ring, the first annular member and the second annular member being configured to be assembled by approaching toward each other along the longitudinal axis and, in an assembled condition, at least one of the first annular member and the second annular member surrounds cut wire ends of the wire braiding unexposed.

An air duct interface is disclosed herein. The air duct interface includes a first air duct including a first opening and a first coupling flange disposed circumferentially around the first opening, a second air duct including a second opening and a second coupling flange circumferentially surrounding the second opening, a first clamping block coupled to the first coupling flange by a first bolt, wherein the second coupling flange is disposed between a portion of the first clamping block and the first coupling flange, and a first adjusting block coupled to the first coupling flange by a second bolt, the first adjusting block engaging the first coupling flange and the second coupling flange.
