[0001] DESCRIPTION

[0002] TITLE: SUPPORT DEVICE

[0003] TECHNICAL FIELD

[0004] The present invention relates to the field of support collars for connecting a device such as a bypass pipe or a pressure or temperature sensor to a main pipeline.

[0005] The invention relates in particular to a support device intended to be mounted on an opening of a pipeline including at least one clamping collar whose diameter adapts to several pipeline diameters.

[0006] The invention makes it possible in particular to adapt the support device in situ to several types of pre-existing pipes.

[0007] PREVIOUS ART

[0008] There are many devices that allow you to create a bypass on a main pipe, to connect either another pipe or a device such as a measuring sensor.

[0009] Prior art bypass devices, also known as "bypass collars" or "support collars", traditionally consist of a rigid base intended to be positioned in a sealed manner on the main pipeline, opposite a bypass orifice. To achieve this, the base may, for example, include a lower portion intended to penetrate the orifice. A seal may also be provided between the base and the orifice of the pipeline. The bypass devices further comprise a flexible flange cooperating with the base to hold it on the pipe.

[0010] US9435476 describes a bypass device comprising an elbow-shaped tubular portion. One end of the elbow has a circular gasket positioned so that the end of the elbow protrudes below the gasket. This end is intended to be inserted into the orifice of the main pipe. The gasket, with a diameter greater than the diameter of the orifice, is intended to rest on the pipe to seal it. The flange is formed by a circular collar having a central opening. The collar is inserted around the tubular portion in order to rest the collar on the gasket. Thus, when the collar is closed around the pipe, it compresses the gasket against the orifice of the pipe.

[0011] However, this system does not allow for the adaptation of several types of devices to the pipeline. Indeed, the opening of the collar has a fixed diameter, which limits the shapes and dimensions of the added devices. Indeed, the device must have a portion of diameter less than or equal to the opening of the collar to be able to slide the collar on the device, and a portion of diameter greater than the opening so that the collar can hold the device against the pipeline.

[0012] Document FR2933764 describes a bypass device comprising a saddle provided with a through opening comprising a thread and allowing, for example, a bypass pipe to be screwed into it. The saddle also comprises means for fixing a flexible strip. The fixing means include a through opening, provided on one end of the saddle and allowing the flexible strip to be inserted and locked using a tab. The other end of the saddle comprises a pivoting metal rod system allowing the flexible strip to be wound. The rod and the end of the strip comprise an opening allowing a screw to be fitted which, on the one hand, blocks the rotation of the rod, and on the other hand, holds the strip on the rod.

[0013] This system has asymmetrical means of fixing the flexible band, which complicates the installation of the device on the pipeline. Furthermore, the implementation of such a device is very complex and expensive.

[0014] The technical problem that the invention aims to solve is therefore to develop a diversion device adaptable to several pipe diameters and whose implementation is easier and less expensive than the devices of the prior art.

[0015] DESCRIPTION OF THE INVENTION

[0016] To solve this problem, the invention proposes to develop a support device comprising at least one clamp made of a flexible material allowing it to be adapted to the shape and size of several types of pipes.

[0017] Against all expectations, the flexible clamps of the invention can also replace the rigid clamps of the prior art intended for installations supporting high pressures. Indeed, a person skilled in the art would naturally think that the flexible clamps of the invention present too great a risk of wear and deformation, in particular when they are subjected to pressures of between 5 and 20 bars and, more precisely, between 8 and 12 bars. A person skilled in the art would thus have avoided using these clamps in order to limit safety risks.

[0018] The invention therefore stems from a discovery according to which such a device can be adapted to a pipeline within which there is high pressure, typically a fire protection installation pipeline in which the pressure is between 5 and 20 bars and more precisely between 8 and 12 bars.

[0019] Thus, the invention relates to a support device intended to be mounted on an opening of a pipeline, said pipeline being included in an installation, said device comprising:

[0020] - a single-piece base with a through hole,

[0021] - a seal intended to ensure the watertightness of the connection between the opening of said pipe and the through hole of said base.

[0022] Such a device is characterized in that:

[0023] - the base also has at least two anchor points, and

[0024] - the device comprises at least one clamping collar comprising:

[0025] • an elongated element intended to partially surround the pipeline, said elongated element cooperating with the base at said anchoring points, and

[0026] • adjustment means independent of the base, allowing the length of the at least one clamp to be adapted so that the device is suitable for being mounted on pipes of different diameters.

[0027] In other words, the adjustment means allow the length of the clamp to be adapted to the diameter of the pipe. For example, the clamp may be long enough to accommodate diameters between 25 and 50 mm.

[0028] To achieve this adaptability, the adjustment means can be in the form of a loop, cooperating with notches made in the elongated element.

[0029] The adjustment means are also independent of the base in order to be positioned in an area distant from the base and thus be able to better withstand the pressure constraints exerted on the opening of the pipeline. In fact, the further the adjustment means are from the base, the better the clamp resists elongation, deformation and breakage.

[0030] Preferably, the adjustment means are installed diametrically opposite the opening of the pipeline, to best compensate for the pressure force exerted on the base, from the opening of the pipeline. The tension being exerted around the pipeline, it is thus better distributed.

[0031] According to the invention, the base is a single-piece, that is to say that the base is a part formed from a single piece, as opposed to a part resulting from the assembly of several constituent elements, as described for example in document WO2018 / 014066. Given the high pressures exerted, the use of a single-piece base makes it possible to guarantee lasting resistance for a guaranteed period of operation, for example for 5 or 10 years of operation.

[0032] The combination of the seal, the adjustment means and the elongated element cooperating with the base, makes it possible to guarantee the tightness of the connection between the pipe and the support device as well as the adaptability of the clamp to different pipe diameters. Indeed, the elongated element makes it possible to press the base against the pipe while the seal, inserted between the base and the pipe, is compressed. Under the traction of the elongated element on the base, the seal deforms to guarantee the tightness of the base around the through hole of the pipe and to match the curvature of the pipe. Thus, the seal under the pressure of the base makes it possible to absorb the differences in curvature between the pipe and the base.Furthermore, the adjustment means make it possible to secure the elongated element in a position in which the seal is compressed so that the compression capacity of the seal also compensates for the lack of progressiveness of the fixing positions of the clamping means.

[0033] It follows that the traction exerted by the elongated element on the base, the modularity of the adjustment means and the deformation capacity of the joint make it possible to adapt the support device to pipes of variable diameters.

[0034] Furthermore, the adjustment means and the elongated element are durable over time, that is to say they do not deform or become unstable over time. The connection therefore remains permanently watertight.

[0035] Furthermore, the combination of the adjustment means and the seal also makes it possible to adapt the length of the clamp to very small variations in the diameter of the pipe, due to manufacturing tolerances. Indeed, among pipes of a given diameter, for example for a diameter of 25 mm, the manufacturer's tolerance may provide a margin of + / - 1 mm within which the diameter of the pipe may vary. Preferably, the notches of the adjustment means have a sufficiently small pitch to allow adaptation to the manufacturer's tolerance.

[0036] The bypass device can be positioned in any orientation relative to the pipeline, as long as it is secured at an opening in the pipeline. For example, the device can be positioned above, below, or to the side of the pipeline.

[0037] The length of the clamps corresponds to the useful portion of the clamps, which is intended to be positioned against the walls of the pipeline. Indeed, a clamp may have a fixed total length, but during adjustment, only a portion of the clamp can be effectively used to hold the bypass device against the pipeline. The non-useful portion can optionally be cut off so as not to hinder maintenance of the installation.

[0038] In addition, clamps that can be adapted to several pipe diameters make it possible to limit the number of different clamp size references, which limits production costs. Furthermore, the adjustment of the clamps can be done in a substantially continuous manner.

[0039] In one embodiment, the support device comprises a single clamping collar and only two anchor points arranged on either side of the base.

[0040] Indeed, a person skilled in the art would naturally think that the flexible clamps of the invention present too great a risk of wear and deformation. He would therefore be led to multiply the number of clamps to reinforce the structure of the clamp. However, the invention makes it possible, against all expectations, to use only a single clamp without increasing the risks of leaks, for example.

[0041] For the purposes of the invention, the "anchor points" correspond to the receiving elements of the base allowing the clamp to be fixed when the clamp is clamped around the pipe. These anchor points may correspond to openings or protrusions, such as lugs.

[0042] According to one embodiment, the anchoring points are through openings oriented in a direction parallel to the main direction of the pipeline, the elongate element being mounted on the base by inserting at least one end of the elongate element into the through openings and forming a loop around the edges of said base.

[0043] According to the invention, the main direction of the pipeline corresponds to the direction parallel to the length of the pipeline.

[0044] This makes it easier to install the clamp on the base because the adjustment method is easily reproducible and requires few tools. For example, it is sufficient to pass through the two openings from bottom to top, so that the elongated element surrounds the pipe. The ends of the elongated element are then pulled from above the base and folded over the ends of the base to tighten the clamp around the pipe. The ends of the elongated element are then brought together and fixed by the adjustment means. This makes it easier to install the support devices on the pipes overall.

[0045] In practice, the through openings may correspond to slots made in the base. Alternatively, the through openings may correspond to the space formed between the base and an axis attached to the base.

[0046] Preferably, the openings are arranged symmetrically with respect to a central axis of the base, thus reducing the risks of incorrect positioning of the support device against the opening of the pipeline.

[0047] According to another embodiment, the two ends of the elongated element are configured to cooperate with the anchoring points arranged on either side of the base, so that the elongated element partially encloses the pipeline after action on the adjustment means.

[0048] In practice, each anchoring point comprises a housing delimited by two lugs, separated by a slot sized to allow the passage of the elongate element, the housing being intended to receive a pin fixed to one end of the elongate element, the lugs being intended to allow the insertion of the pins into the housings before action on the adjustment means and to block the extraction of said pins after action on the adjustment means.

[0049] This makes it easier to install the clamp on the base because the adjustment method is easily reproducible and requires few tools. The elongated element simply surrounds the pipe and its ends, equipped with a pin, are locked into the base's housings. The clamp is then adapted to the pipe diameter using the adjustment means. This makes installing the support devices on the pipes faster overall.

[0050] Alternatively, each anchor point comprises a lug intended to cooperate with a hole provided at the ends of the elongated element.

[0051] The clamp is mounted on the base by fitting the elongated element around the pipe so that its ends, fitted with a hole, are locked onto the lugs of the base. The clamp is then adapted to the diameter of the pipe using the adjustment means.

[0052] The elongated element can take different forms. In a first form, the elongated element is a strip, that is, similar in shape to a ribbon. Alternatively, the elongated element is a cable, thinner but nonetheless just as strong. Indeed, the invention makes it possible to use elongated elements with reduced width without compromising the safety of the installations.

[0053] In practice, the elongated element is formed from a metallic material, because surprisingly, the invention makes it possible to use different metallic materials for the production of the elongated element without compromising the safety of the installations.

[0054] Advantageously, the means for adjusting the length of the at least one clamping collar comprise marks making it possible to compress the seal at a predetermined rate.

[0055] This embodiment makes it easier to install the clamp and eliminates the risk of errors. The technician can rely on visual cues during installation, indicating how far to tighten the clamp so that the seal is optimally compressed to avoid leaks, depending on the diameter and operating pressure. Alternatively, these cues can be combined with or replaced by a device for measuring the clamp adjustment tension.

[0056] For both embodiments, the openings are preferably arranged symmetrically with respect to a central axis of the base. This system thus reduces the risks of incorrect positioning of the support device against the opening of the pipeline.

[0057] Furthermore, in a preferred embodiment, the adjustment means are integral with one end of the elongated element. Indeed, this embodiment makes it possible to tighten the support device on the pipeline by performing a simple pulling movement of the free end of the elongated element.

[0058] A clamp with the above characteristics advantageously simplifies and reduces the time required to install the support device on the pipeline.

[0059] However, the locking system of the elongated element could be different without this affecting the proper functioning of the invention.

[0060] According to another aspect, the invention relates to an installation including:

[0061] - at least one pipe having at least one opening, and - at least one support device as described previously.

[0062] Preferably, the pipe is a painted or pre-painted pipe on its internal and external faces, that is to say that the pipe has a paint covering its internal and external faces. The paint helps protect the pipe from damage, particularly that caused by rust. The applied paint must allow drilling and cutting without flaking, thus considerably reducing manufacturing times in the workshop. Indeed, the painting phase after manufacturing usually carried out in known processes is eliminated.

[0063] Preferably, the pipeline paint includes an epoxy polymer binder, which is particularly resistant to drilling and cutting. Typically, the installation may be a fire protection installation in which it is desired to measure a value, such as a pressure value using a pressure gauge.

[0080] DESCRIPTION OF EMBODIMENTS

[0081] As illustrated in Figure 1, a bypass device 100, 200, 300, 400, 500, 600, 700 is mounted on an installation comprising at least one pipe 40. The pipe 40 is configured to contain a fluid such as water or gas. To do this, the pipe 40 is preferably made of steel, stainless steel, copper or chlorinated polyvinyl chloride. In certain embodiments, the pipe 40 may be configured to withstand pressures of the order of ten bars, for example between 5 and 20 bars and preferably between 8 and 12 bars. In addition, the diameter of the pipe 40 may vary, typically between 20 and 600 mm, also called by the acronym “DN 20” or “DN 600”.

[0082] In order to integrate the bypass devices 100, 200, 300, 400, 500, 600, 700 of the invention, one or more openings are provided in the pipes 40. The openings are for example circular, with a diameter between 10 and 500 mm, also called by the acronym “DN 10” or “DN 500”. The diameter of the opening is sized according to the diameter of the pipe and the device to be integrated.

[0083] As illustrated in Figure 1, the device 100, 200, 300, 400, 500, 600, 700 comprises a single-piece base 24A-24G having a substantially flat parallelepiped shape with a thickness of between 0.5 and 1.5 cm. Alternatively, the lower face of the base 24A-24G may have a slight curvature, as illustrated in FIG. 1. The curvature of the lower face is chosen to adapt to the curvature of the larger diameter pipe 40 on which the device 100, 200, 300, 400, 500, 600, 700 can be adapted. The base 24A-24G may be directly obtained by a molding process, a material subtraction process, such as machining or laser cutting, or by an additive process, such as 3D printing. The base 24A-24G further has a through opening 26 with a diameter of between 10 and 500 mm.

[0084] Advantageously, a seal 28 is positioned opposite the lower face of the base 24A-24G, typically between the base 24A-24G and the pipe 40, so as to surround the openings of the base 24A-24G and the pipe 40 respectively. For example, the seal 28 is a rubber O-ring with a thickness of between 0.2 and 0.7 cm. Alternatively, for pipes of larger diameter, the seal may include lips and have a thickness of between 0.5 and 3 cm.

[0085] A device such as, for example, a bypass pipe, a fire protection nozzle or a pressure gauge, as illustrated in FIGS. 8 to 19, may be attached to the base 24A-24G by aligning the device with the through opening 26 of the base 24A-24G. For example, the device may have a male portion having a thread and cooperating with a second thread, formed in the walls of the through opening 26 of the base 24A-24G. The device may thus be screwed onto the base 24A-24G.

[0086] The clamp(s) 30 make it possible to fix and maintain the device on the pipe 40.

[0087] The clamp(s) 30 comprise an elongated element, such as for example a strip with a width of between 0.5 and 2 cm or a cable with a diameter of between 0.2 and 1 cm. Alternatively, the elongated element may be a “serflex” type clamping element, made of a metallic material. The clamps 30 also comprise means 32 for adjusting the length and tightening of the clamp 30. The base 24A-24G may be provided with one or more clamps 30 depending on the requirements of the installation and the diameter of the pipe 40.

[0088] The adjustment means 32 are independent of the base 24A-24G.

[0089] For example, the adjustment means 32 may also be independent of the elongate element 31. They may consist of one or more added parts which may be fixed or fitted onto the elongate element 31 in order to hold it in place.

[0090] As illustrated in Figures 1 to 3, the clamping collar 30 may be in the form of a metal strip 31 and the adjustment means may include a loop 33A, independent of the strip 31, comprising a housing 35 in which the ends of the strip 31 are inserted. Self-drilling screws 34 make it possible to pierce the different thicknesses of strip 31. Advantageously, the loop 33A has an opening 36 making it possible to receive the lower portion of the body of the screw 34.

[0091] Thus, the elongated element can be directly adapted to the diameter and tolerance of a pipeline 40 by creating the necessary opening so that the seal 28 is compressed with an optimal compression ratio and the connection between the pipeline and the support device is made as watertight as possible. The adjustment is made "to measure" and the adjustment possibilities are almost continuous.

[0092] Alternatively, in an embodiment not shown in the figures, the elongate element may be a metal strip comprising openings arranged regularly and closely together along the elongate element. In order for the elongate element to be directly adapted to the diameter and tolerance of a pipeline, the pitch between the openings is preferably less than or equal to the manufacturer's tolerance. Typically, if the pipeline has a diameter of 25mm and the tolerance is + / - 1mm, the pitch between the openings is less than or equal to 1mm. Thus, the joint can be compressed with an optimal compression ratio, and the connection between the pipeline and the support device is made as watertight as possible.

[0093] In order to fix the base 24A on the pipe 40, it is positioned on the opening of the pipe 40. The two ends of the strip 31 are inserted, in an upward movement, through the anchor points, materialized by lateral openings 25A so that the strip 31 surrounds the pipe 40. The ends of the strip 31 are then pulled from above the base 24A and folded over the ends of the base 24A to tighten the clamp 30 around the pipe 40. The ends of the strip 31 are then brought together, thus forming a loop around each edge of the base 24A. The ends of the strip 31 are then fixed together by the adjustment means 32.

[0094] Thus, as illustrated in Figure 3, the loop 33A is positioned on a first thickness of strip 31. The ends of the strip 31 are then folded down and inserted into the housing 35 of the loop 33A, then tightened so as to effectively hold the base 24A on the pipe 40. To do this, the ends of the strip 31 protrude on each side of the housing 35 over a length of at least 1 cm. The ends of the strip 31 thus overlap at the level of the body 37 of the loop 33A. The screw 34 is finally inserted at the level of this overlap and pierces the two thicknesses formed by the ends of the strip 31. Alternatively, as illustrated in Figures 4a to 4d, the adjustment means 32 are integral with one end of the elongate element. Thus, the clamping collar 30 may be in the form of a metal strip 31 and the adjustment means may include a loop 33B comprising a housing 35, fixed to the end of the strip 31.

[0095] The housing 35 may take the form of a tube of parallelepiped section, intended to allow the passage of a part of the metal strip 31. Furthermore, fixing means, such as a self-drilling screw 34, may be placed on the housing 35, perpendicular to the length of the tube and to the direction of movement of the strip 31 in the tube, so as to restrict the movements of the strip 31 when it is compressed around the pipe 40 and inserted into the tube.

[0096] In an alternative embodiment not shown, the fixing means include a ball contained in the tube and intended to block the movements of the elongate element. To do this, the tube has a variable section. Typically, the section of the tube narrows from dimensions greater than the diameter of the ball to dimensions substantially equal to the diameter of the ball. Thus, when the elongate element slides in the tube, the ball is driven in a direction opposite to the direction of insertion of the elongate element, towards the part of the tube with reduced dimensions, where it is blocked. The ball thus also blocks the movements of the elongate element.

[0097] The spaces 25B of the base 24B are used to create attachment points for the strap 31. To do this, as illustrated in FIG. 4a, the end of the strap 31 not provided with the loop 33B is inserted according to a first movement M1 to surround a first attachment point of the base 24B. This movement M1 is carried out by inserting the strap 31 into the space 25B from the upper face of the base 24B to the lower face of the base 24B until the strap 31 arrives along the pipe 40.

[0098] The strip 31 is then moved around the pipe 40 to the second attachment point of the base 24B. As illustrated in FIG. 4b, the strip 31 is then introduced into the space 25B following the movement M2 to surround the second attachment point of the base 24B. This movement M2 is carried out by inserting the strip 31 into the space 25B from the lower face of the base 24B to the upper face of the base 24B until the strip 31 arrives along the pipe 40.

[0099] The strap 31 is then introduced into the loop 33B following the movement M3, illustrated in Figure 4c. The clamp 30 is then compressed around the pipe 40 by pulling on the end of the strap 33 after it has passed into the housing of the loop 33B, according to the movement M4.

[0100] In certain embodiments, when the desired compression tension of the strip 31 is obtained, means for fixing the strip 31 in the housing can be inserted into the loop 33C by means of an action in a direction M5, perpendicular to the length of the housing 35, as illustrated in FIG. 4d. Subsequently, the remaining end of the strip 31 protruding from the loop 33C can optionally be cut.

[0101] Furthermore, the elongated element 31 may also have notches or grooves making it possible to accommodate or block the adjustment means 32.

[0102] Advantageously, the clamping collar 30 also has markings making it possible to adapt the tightening to the pressure prevailing in the pipe 40. Similarly, the support device 100, 200, 300, 400, 500, 600, 700 can also include an integrated device for measuring the tension of the strap 31. Similarly, an external device can also be used to check the tightening tension.

[0103] There are several embodiments for attaching the clamp 30 to the base 24A-24G.

[0104] As illustrated in Figure 1, in a first embodiment, the base 24A has a parallelepiped shape with, for example, threads at the corners. The base 24A has a length of between 2 and 10 cm and a width of between 2 and 5 cm. The length of the base 24A is intended to be positioned in a direction perpendicular to the main direction D of the pipe 40.

[0105] The base 24A has at its ends two lateral grooves 25A formed in the thickness of the base 24A, of substantially parallelepipedal shape and intended to allow the passage of the strip 31 of the clamping collar 30.

[0106] A bore 46 may also be provided on the lower portion of the grooves 25A allowing the groove 25A to open to the outside. This bore 46 allows the strip 31 to better adapt to the shape of the pipe 40.

[0107] Alternatively, as illustrated in Figures 4a to 4d, the base 24B may have two recesses at its ends, making it possible to create the opening 25B. The end of the recesses may comprise two pins 43. Thus, the strip 31 of the clamping collar 30 may pass through the openings 25B and form a loop around the pins 43. According to another example, the base 24B may have means for fixing two pins 43 attached on either side of the base 24B. The pins 43 are positioned so as to leave a free space 25 between the edges of the base 24B and the pins 43. This space 25B is intended to allow the passage of the strip 31 of the clamping collar 30, the latter then being able to form a loop around the pins 43.

[0108] As illustrated in Figures 5 to 7, in a third embodiment, the base 24C has a substantially hexagonal shape with a length of between 2 and 8 cm and a width of between 2 and 5 cm. The length of the base 24C is intended to be oriented in a direction perpendicular to the main direction D of the pipeline 40.

[0109] The base 24C further has two pairs of lateral grooves 25C arranged on either side of the base 24C in the thickness of the base 24C, of ​​substantially parallelepiped shape and intended to allow the passage of two clamping collars 30. Preferably, the grooves are spaced 1 to 3 cm apart. This type of base 24C is used for pipes 40 of larger diameter, typically greater than DN50.

[0110] The mounting of the clamps of the two clamps 30 is carried out in the same manner as described in figures 4a-4d, the clamps 30 being able to be mounted simultaneously or one after the other.

[0111] As illustrated in Figures 8 to 10, in a fourth embodiment, the base 24D comprises two anchoring points 25D, on either side of the base 24D. Each anchoring point 25D comprises a housing 49 having a depth of between 0.5 and 1 cm and dimensioned to accommodate an axis 47 with a length of between 1 and 3 cm and a diameter of between 0.1 and 1 cm. In this fourth embodiment, the housing 49 extends over the entire width of the base 24D. The housing 49 is bordered by two lugs 48. Preferably, the upper portion of the lugs 48 may be rounded or even beveled to allow the movement of Tax 47 to be guided towards the housing 49. The two lugs 48 are separated by a slot, sized to allow the passage of the cable 39, but to prevent the passage of Tax 47, the latter thus remaining blocked in the housing 49, retained by the lugs 48.

[0112] As illustrated in Figures 11 to 13, in the fifth embodiment, the housing 49 of the anchor points 25E may have a shallower depth without causing the extraction of the element 47. The width of the slot may also be adapted to the width of the elongate element. In this fifth embodiment, the slot is sized to allow the passage of a strip 31.

[0113] As illustrated in Figures 14 to 16, in a sixth embodiment, the base 24F has anchoring points 25F comprising a lug 50 intended to cooperate with a hole provided at the ends of the elongate element 31. In order to mount the elongate element on the base 24F, the holes of the elongate element 31 are inserted on the lugs 50 so as to also surround the pipe 50, then the clamping collar 30 is adapted to the diameter of the pipe via the adjustment means 32.

[0114] As illustrated in Figures 17 to 19, in a seventh embodiment, the base 24G has a housing 49 bordered by two lugs 48 separated by a slot, sized to allow the passage of the width of the elongate element 31. The slot is covered with a plate connecting the two lugs 48, thus creating a space with a thickness of between 0.05 and 0.2 cm, not allowing the passage of the axis 47, but only that of the elongate element 31. Thus, in order to insert the elongate element 31, the axis 49 must first be removed, then the terminal portion of the elongate element 31 is inserted into the slot covered with the plate. The axle 47 is then fixed to the end of the elongate element 31, for example by sliding it into a loop created at the end of the elongate element 31. Finally, the axle 47 is inserted into the housing 49. The axle 47 cannot therefore be extracted from the housing 49 because it is blocked by the presence of the plate.To conclude, the invention makes it possible to obtain a bypass device adaptable to several pipe diameters and whose implementation is easier and less expensive than the devices of the prior art.
