- the proximal side lp rests on the palm of the hand ensuring a good grip of the comb.
- the comb 1 does not have the opening 5.
- the operator's thumb rests on the recto face Ir of the comb while the other four fingers of the operator's hand are resting on the verso verso lv, considering that the proximal side lp can be resting on the palm of the hand. It should be noted that this gripping position of the comb can be used even for the comb provided with the opening 5.
- the thumb rests on the recto face Ir of the first part la of the comb located between the opening 5 and the proximal side lp while the other four fingers of the hand are resting on the back face lv of this first part la of the comb located between the opening 5 and the proximal side lp.

- This separation system 8 comprises at least one control and in the example illustrated, two controls 11a, 11b for moving fingers 12 engaged between the teeth 4 and adapted to exert a force on the plugs 2 to detach them from the teeth 4.
- the separation system 8 comprises a drawer 13 resiliently biased and guided to slide relative to the body 7 in a direction parallel to the direction of extension of the teeth 4, that is to say to the main direction X.
- This drawer 13 is provided with fingers 12 and controls 11a, 11b, of which a support in translation, ensures the sliding of the fingers 12 in the direction of the pointed distal parts 4p to eject the plugs 2 from the teeth 4.
- the drawer 13 is therefore able to occupy a first so-called rest position for which no force is exerted on the controls 11a, 11b and a second so-called ejection position for which pressing on one and / or the other of the controls 11a, 11b leads to the expulsion of the plugs 2 with respect to the teeth 4.

- the fingers 12 are spaced apart to be engaged between the teeth 4. More precisely, the fingers 12 of the drawer are engaged between the flat lateral faces 4i of the teeth 4.
- the fingers 12 are guided in sliding with clearance, between the teeth 4.
- Each finger 12 projects out from the distal side of the plate 13a in a direction parallel to the main direction X.
- the fingers 12 are located set back from the distal end of the teeth 4 when the drawer 13 occupies its rest position ( Figures 1, 2, 4 and 5) while in position of ejection, the fingers 12 extend substantially to the pointed distal parts 4p of the teeth 4 ( Figures 6 and 7E).
- Each finger 12 has a front face 12i and on the other hand, a rear face 12j turned on the same side respectively as the front face lr and the back face lv.
- Each finger 12 comprises a segment 12a for connection to the plate 13a of the drawer, extending in a direction parallel to the main direction X.
- This connection segment 12a is connected by a segment intermediate 12b which is extended in a direction parallel to the main direction X, by a thrust segment 12c, the free end or edge of which is intended to bear on the stopper 2 to release it from the teeth 4.
- each intermediate segment 12b starts from the plate 13a of the drawer in the opposite direction from the front face lr so that the thrust segment 12c is located behind the front face lr.
- the rear face of the thrust segment 12c of the fingers 12 is located in a plane extending coplanar with the rear face 4b of the teeth 4 of the comb.

- each control 11a, 11b of the drawer 13 is advantageously accessible from the first part la of the comb so as to avoid contamination of the operator during actuation of the control.
- the drawer 13 comprises, as a control, a support button 11a accessible from the proximal side lp of the first part la of the comb.
- this support button 11a is located in a corner of the proximal side lp and more precisely in the upper right corner when the comb is seen from its front face lr, with its teeth 4 positioned horizontally.
- this key support 11a is protruding from the plate 13a of the drawer to extend over a part of the proximal side lp and the lateral side 11. It should be noted that the plate 7a of the body 7 has a cutout 7d for the housing of the press button 11a.

- the drawer 13 can be moved in translation from its rest position to its ejection position, by a force exerted at the proximal side of the comb and / or the reverse side of the comb.
- the slide 13 is resiliently biased, to pass, during the removal of the bearing force on the controls 11a, 11b, from the ejection position to the rest position.
- the drawer 13 automatically returns to its rest position by means of an elastic return system 17 of all types known per se.
- the elastic return system 17 comprises a bending deformable blade 17a, one end of which is linked to the slide 13 in a direction parallel to the transverse direction Y. The other end of this deformable blade 17a rests on a stop 7b adjoining the body 7 so that it undergoes the force to be returned to the spool 13 during the sliding movement of the spool in the main direction X.
- the drawer 13 is urged by a return force bringing it back to its rest position.
- the comb 1 is provided with an end stop for the slide 13 limiting its sliding to a position corresponding to the position of ejection of the plugs.
- This limit stop can be produced in any suitable manner.

- the tubes 3 and consequently the plugs 2 are aligned parallel to the transverse direction Y, with a spacing pitch corresponding to the spacing pitch between the teeth 4 of the comb 1.
- the comb 1 positions it to orient the teeth 4 in a direction parallel to the transverse direction Y and in a position such that a tooth 4 is located in line with each plug 2 to be removed (Figure 7A).
- the operator then engages the teeth 4 inside the cavities 2b of the plugs 2 to ensure that the plugs are engaged by the pointed distal parts 4p of the teeth.
- the engagement of the pointed distal parts 4p of the teeth 4 in the wall 2c of the plugs can be facilitated if the comb occupies with respect to the vertical plane, an inclined position (movement M1) as illustrated in FIG. 7B .
- Such an inclined position of the comb allows the engagement of the teeth 4 inside the cavities 2b of the plugs while allowing the insertion of a part of the plugs in the recesses 9 presented by the teeth 4.
- the caps 2 are hung on the teeth 4 of such a comb which can be moved to be positioned above a recovery receptacle 18 ( Figure 7E).
- the operator presses with at least one finger on the control 11a and / or 11b to move the drawer 13 in translation, the fingers 12 of the drawer of which push on the caps 2 leading to separate them completely from the teeth 4.
- the caps 2 are automatically and simultaneously ejected from the comb 1 to be recovered in the recovery receptacle 18.
- the gripping of the comb 1 for its use can be achieved in different ways.
- the first part la of the comb is taken by a hand of the operator whose fingers except the thumb are engaged through the opening 5 so that the first part la of the comb located between this opening 5 and the on the proximal side lp is supported, by the back face lv with the palm of the hand and, by the front face, with the four folded fingers of the operator's hand.
- the proximal side lp of the comb can rest on the palm of the hand.
- the thumb of the hand of the operator who has the comb in his hand can easily press the support button 11a of the drawer located in the upper rear corner of the comb, to ensure the detachment of the plugs by compared to teeth.
- the operator's thumb rests on the front face lr while the other four fingers of the operator's hand are resting on the back face lv, considering that the proximal side lp can rest on the palm of the hand.
- the sliding of the drawer 13 can be obtained by a force exerted by the fingers on the support rib 11b and / or the support button 11a.
