Second, as long as both elements are accessible from the outside, there is a possibility that they will be separated from the part with them due to direct impact
In particular, the perforated tabs may become displaced or detached from the clamping sleeve

Embodiment Construction

[0045] figure 1The ends of two tubes 1 and 2 are shown, aligned along their common axis A, which is also the general axis of the device (in particular, the clamping and sealing sleeves of the device) . The two pipes have substantially the same diameter and are coupled together by a coupling device comprising a clamping sleeve 10 and a sealing sleeve 20 inside the clamping sleeve 10 . For example, as described in application WO 00 / 75548, the sealing sleeve is split axially and thus has a radially turned axial groove 11 defined by the assembly lip. In order to achieve the clamping, the assembly lips facing each other can be brought together by fasteners, in particular by bolts cooperating with nuts. In this example, two fastening assemblies are provided, taking into account the axial length of the sleeve. Thus, the first assembly lip comprises two turned-out lugs 12A and 12B separated by a groove 12C which separates the lugs 12A and 12B from each other when they are drawn clo...

Abstract

The device comprises a sealing sleeve (20) that can be arranged about the facing ends of two tubes (1, 2) and a clamping sleeve (10) into which the sealing sleeve extends. One of the elements comprising the sealing sleeve (20) and the clamping sleeve (10) has at least one retaining member (32A, 32B) capable of engaging, in axial retention inside the clamping sleeve, with a retention surface (1'A, 2'A) of one of the tubes covered by the clamping sleeve.

Description

technical field [0001] The present specification relates to a coupling device for coupling together two aligned pipes of substantially the same diameter in a sealed manner, the device comprising: a sealing sleeve adapted to be disposed around facing ends of the two pipes, and a clamping sleeve within which the sealing sleeve extends. Background technique [0002] Devices of this type are known, for example, from patent applications WO 00 / 75548 and WO 2006 / 109002. [0003] The known device is satisfactory with regard to clamping and sealing. However, as a matter of practicality, it may be advantageous to be able to pre-attach the device to at least one of the pipes to facilitate assembly and to ensure proper positioning of the device relative to the pipe before commencing to tighten the device. [0004] Document US 7 458 619 proposes a solution that makes this pre-attachment possible, in which a pipe has a protruding button, and the clamping sleeve has tabs with holes, the ...
