    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
    In Figures 1 to 7, there is shown a zipper with an increased indication according to the present invention. The zipper io comprises interlocking teeth 1, a slider 2 and a pair of zipper bands 3. The interlocking teeth 1 are fixed to the respective lateral edges of the zipper strips 3 in a staggered manner using injection molding technology. Each interlocking tooth 1 comprises a tooth body 11, a front end part 12, with engagement, extending on a front side of the tooth body 11, and a rear extension end part 13, s' extending on an opposite rear side of the tooth body 11. The rear extension end portion 13 includes a track 131 and an augmented portion 132. The track 131 of the rear extension end portion 13 of the tooth interlocking device 1 comprises a smooth track base 1311 having a reduced thickness, a vertical sliding support wall 1312, situated on a lateral side of the smooth track base 1311 and forming a body with the rear side of the tooth body 11, and an L-shaped space 1313 defined between the smooth track base 1311 and the vertical wall 1312 of the sliding support.
    The cursor 2 comprises a cursor body 21, a lower clamping panel 22 and an upper clamping panel 23. The slider body 21 comprises a central block 211 forming a spacer, a nose 212 and a pull tab 213. The central block 211 forming a spacer of the slider body 21 has opposite upper and lower sides, connected respectively to the lower clamping panel 22 and to the upper clamping panel 23. The nose 212 is inserted through an assembly hole 2131 of the pull tab 213 and its two opposite ends are fixed on the upper clamping panel 23. The lower clamping panel 22 comprises two opposite vertical lateral flanges 221, each extending upwards from two opposite lateral sides of this panel. The upper clamping panel 23 comprises two opposite lateral wing-shaped parts 231. An open space 232 extended is defined between the planar lateral portions 231 in the shape of a wing of the upper clamping panel 23 and the vertical lateral edges 221 of the lower clamping panel 22, located near an integrated internal surface 2311 of the portion flat lateral 231 wing-shaped; more specifically, each open space 232 extended is defined between the integrated internal surface 2311 of the planar lateral part 231 in the shape of a wing of the upper panel 23 of corresponding clamping and the strip 3 of corresponding zipper.
    In use, the cursor 2 is connected to the teeth 1 which are interlocked with each vertical lateral edge 221 of the lower panel 22 for clamping in abutment against the tracks 131 of the rear extension parts 13 of the interlocking teeth 1. At this stage, the parts front end 12 with engagement of the interlocking teeth 1 present on the two zipper strips 3 are separated by the central spacer block 211 from the cursor body 21 of the cursor 2. When the user pulls on the tab traction 213 for interengaging the teeth 1 with interlocking, the lower clamping panel 22 which the cursor 2 comprises is moved along the tracks 131 of the end portions 13 with rear extension of the locking teeth 1. During the movement of the cursor 2 from the respective lower ends of the zipper strips 3 to the respective opposite upper ends of the zipper strips 3 The front end parts 12, with engagement, of the interlocking teeth 1 located on a zipper strip 3 are each forced towards the front end portions 12, with engagement, of the interlocking teeth 1 located on the 'other zipper band 3. Due to the guidance produced by the internal walls of the vertical lateral flanges 221 of the lower clamping panel 22 that the slider 2 comprises, the front end portions 12, in engagement, of the teeth 1 with interlocking located on a strip 3 of closure slide are each forced to engage with the front end portions 12, engagement, teeth 1 interlocking located on the other strip 3 of zipper. The user, when he wishes to open the zipper, pulls on the pull tab 213 in the opposite direction to move the central spacer block 211 of the cursor body 21 of the cursor 2 between the front end portions 12 , with engagement, teeth 1 with interlocking located on a zipper strip 3 and the front end portions 12, with engagement, teeth 1 with interlocking located on the other strip 3 with zipper, thus unlocking the teeth 1 interlocking.
    The design of the rear extending end portions 13 of the interlocking teeth 1 increases the clamping depth of the interlocking teeth 1 in the zipper bands 3, thereby improving the clamping stability between the interlocking teeth 1 and the bands 3 zipper closure.
    In addition, the design of the extended open space 232 which is defined between the integrated internal surface 2311 of the planar side portions 231 of the wing of the upper clamping panel 23 and the zipper strips 3 allows the raised portions 132 end portions 13 with rear extension of the interlocking teeth 1 to be freely configured, so as to present a significant visual indication. In addition, the thickness of the increased portions 132 is approximately equal to half the thickness of the tooth bodies 11 of the interlocking teeth 1. In addition, the junction between the increased portion 132 and the tooth body 11 of each interlocking tooth 1 has a smooth surface, facilitating the design allowing an indication of the increased portion 132. The design allowing an indication of the increased portion 132 of the rear extending end portion 13 of each interlocking tooth 1 can be a geometric figure, a number, a symbol or an alphabetical letter or word. FIG. 1 illustrates the increased portions 132 of the end portions 13 with rear extension of the interlocking teeth 1 in the form of English words.
    In addition, when the cursor 2 moves along the tracks 131 of the rear-extending end portions 13 of the latching teeth 1, the vertical lateral flanges 221 of the lower clamping panel 22 which the cursor 2 comprises slide in the space 1313 while being kept in contact with the smooth track bases 1311 and the vertical walls 1312 of sliding support which comprise the tracks 131 of the end portions 13 with rear extension of the teeth there interlocking. Because the material of the smooth track base 1311 has a hardness characteristic, the smooth track base 1311 cannot be engaged in the slider 2, preventing the slider 2 from getting stuck during its sliding movement.
