(40) Referring to the drawings, the disclosure will now be described in more detail. FIG. 2A illustrates an exploded view of a tube connector arrangement 230, in accordance with an embodiment 200 of the present disclosure. The tube connector arrangement 230 is coaxially provided at the outer tube surface 2106. As shown in FIG. 2A, the tube connector arrangement 230 includes a first ferrule 2302, a second ferrule 2304, a position locator 2308 and a compression nut 2306. The position locator 2308 is adapted to either temporarily or permanently fasten to the outer tube surface 2106 of a tube 210, at a predetermined depth from the first tube end 2102.
(41) FIG. 2B illustrates the position locator 2308 for use with the tube connector arrangement 230 of FIG. 2A, in accordance with an embodiment of the present disclosure. As shown in FIG. 2B, the position locator 2308 has a fastening means 2310 adapted to fasten the position locator 2308 to the outer tube surface 2106 of the tube 210. In accordance with an embodiment of the present disclosure, the fastening means 2310 includes one or more elastic projections projecting from an inner position locator surface 2312 of the position locator 2308. When the position locator 2308 is introduced to the tube 210, the one or more elastic projections engage with the outer tube surface 2106 of the tube 210. The engagement of the one or more elastic projections prevent sliding of the position locator 2308 along the outer tube surface 2106.
(42) In another embodiment, the inner position locator surface 2312 is an expandable surface. Further, inner diameter of the position locator 2308 is smaller than diameter of the outer tube surface 2106 of the tube 210. So when, the position locator 2308 is introduced to the tube 210, the inner position locator surface 2312 is expanded to move the position locator 2308 along length of the tube 210. At the predetermined depth, the inner position locator surface 2312 is released, such that, the inner position locator surface 2312 contracts to engage with the outer tube surface 2106 of the tube 210. It would be appreciated by a person skilled in the art, that the fastening means 2310 is not limited to the embodiments discussed above but also may include any such means capable of either temporarily or permanently fastening the position locator 2308 to the outer tube surface 2106 of the tube 210. Further, the position locator 2308 has a position locator flange 2314 adapted to receive one or more of the first ferrule 2302 and the second ferrule 2304.
(43) FIG. 2C illustrates a position locator guide 240 for installation of the position locator 2308 onto the tube 210 of the tube connector arrangement 230 of FIG. 2A, in accordance with an embodiment of the present disclosure.

The elongate portion 2402 is a hollow portion and has an inner diameter greater than the diameter of the outer tube surface 2106 of the tube 210. Further, the cap 2404 is substantially solid. The elongate portion 2402 has a length equal to the predetermined depth. In use, the position locator 2308 is first introduced coaxially to the tube 210 such that the position locator is near the first tube end 2102. The tube 210 engages with the position locator guide 240 by being inserted inside the elongate portion 2402, such that, the outer tube surface 2106 is exposed below the predetermined depth from the first tube end 2102. Further, the position locator 2308 is pushed from the end along the outer tube surface 2106 to locate/place the position locator 2308 at the predetermined depth from the first tube end 2102. Thus the position locator guide 240 allows easy location of the position locator 2308 along the outer tube surface 2106, at a predetermined depth from the first tube end 2102.
