bution 1.

  This housing comprises a body of generally parallelepiped shape with four side walls 2, 3, 4 and, a lower wall 6 and an upper wall 7.

  Walls 2 and 5, in the vicinity of the inner wall

  6, support an axis 9 on which is wound a

  strip 10, one face 11 of which comprises, at regular intervals

  liers, dough pieces 12 of an adhesive pasty material. The two sides of the strip 10 are coated with a film so that the dough pieces 12 can adhere, but can also be detached.

  On a spindle 15 is fixed a drum 16 with inter-

  position of a free wheel 17 so that said drum cannot

  turn only in the direction of arrow f (see figure 6).

  The drum 16 has two cheeks 18 which have a diameter greater than that of the drum and which comprise

  radially and evenly spaced from the pins 19.

  On the inner face of the wall 2 is fixed an S15 dovetail slide 21 in which slides a corresponding heel 22 of a rack 24 which cooperates, on the one hand, with the external toothing of the freewheel 17 and, on the other hand, with a pinion 26 secured to an axis 27 guided in a bearing 28 of the wall 2 and at the end of which is

  wedged a movable lever 29 between two stops 31 and 32.

  The rack 22 is pushed by a compression spring 34 in order to bear against a stop 35 in a position corresponding to the high position of the lever

  29, position in which it bears against the stop 31.

  The face 4 of the housing 1 has, in the vicinity of the wall 7, an opening 36 and on the walls 2 and 5 are provided guides 37 which pass through the said opening and extend to the vicinity of the lower wing 39

U profiles 40.

  The U-shaped sections 40 are opposite and pre-

  feel a straight part 40a, a V-shaped part 40b and a straight part 40c extending in the extension

from part 40a.

  The wing 39 of the part 40a is pierced with two slots through which an endless chain 41 passes.

  provided with regular spikes 42, said chain

  not being guided on pinions 43 whose axes are sup-

  carried by yokes 44 integral with the profiles 40.

  The part of the V 40b, adjacent to the part 40z, has in its wing 39 two slots through which is guided an endless chain 41a provided with pins 42.a regularly spaced, and guided on pinions 43.a carried

  by yokes 44a integral with said sections 40.

  Chains 41 and 41a slide on wing 39

  profiles 40, the pinions 43 and 43a being idle.

  The lower ends of the profiles 40 are

  integral with reinforcement bars 47 integral with the housing.

  The strip 10 (see FIG. 2) has, in the vicinity

  swimming its edges, perforations 48 regularly spaced

  cées, intended to cooperate with the pins 19 and 42, and is divided into sections 50 which are delimited by a continuous rupture initiator 51, each section 50 being divided into two parts by a groove 52 with a central hole 53, a

  hole 54 being provided in the vicinity of each end of cha-

that stretch.

  As seen in Figures 1 to 7, the strip is wound on the axis 9, is guided on the pins by its edges, passes over the guides 37 and is engaged in the

  profiles 40, its holes 48 being engaged on the pins 42.

  When the lever 29 is lowered, the pinion 26 drives the rack 22 which drives the pinion 17 in the direction of arrow f, the spring 34 being compressed. The lowering of the lever 29, from the stop 31 to the stop 32, causes the strip 10 to move by a step corresponding to a length of section 50. When the lever 29 is released, the spring 36 pushes the rack 22 which returns to its initial position by driving the pinion 26 which brings back the arm 29

  against the stop 31. During this return stroke from the

  mesh 22, the freewheel 17 turns without driving the drum

bour 16.

  FIGS. 8 to 11 show a tool 60 intended to be used for placing a section of strip 50 in a

case 70 (see figure 12).

  The tool 60 consists of a hollow handle 61 having a longitudinal groove 62 in which is

  mobile a slider 63 secured to two branches 65 to the ex-

  hoppers from which are articulated rods 64 whose other ends are articulated at one end 67

  bars 70 pivotally mounted on axes 68 and ter-

undermined by hooks 69.

  Each bar 70 passes through a light 71 and

  has, at its end 67, a heel 72 on which it

  hooks one end of a tension spring 73 whose au-

  the end is fixed to a bar 74 from the inside of the

body.

  Thanks to this arrangement, the hooks 69 can

  wind occupy two positions, a first position in the-

  which they protrude outside the body of the tool and abut against the corresponding end of the light (see FIG. 8) and a second position in which the cursor 63 is moved in the direction of the arrow g, they are erased in the body (see Figure 9) against the action of the tension springs 73. The tool 60 is terminated by a thinned part 77 in the central part of which extends

a point 78.

  FIG. 12 represents a case 70 intended to be inserted in a housing of a box element of an electrical connector, said case comprising a body 81 with a bottom 82, two side walls 83, a flap 84 and

  partitions 85 delimiting compartments 86.

  Each compartment 86 is intended to receive an electrical contact member 87 crimped, at one end,

of an electrical conductor 88.

  Organ 87 can be a male organ as well

  or female and case 70 can have a number of compar-

any kind.

  The worker has, at his disposal, a distribution box 1, cases 70 and a tool 60. The distribution box 1 is provided with a strip 10, a section 50 of which is located in the V 40b of the profiles 40. L worker presents the tool 60 so that the point 78 is inserted into the hole 53 and pushes the tool so that the section 50, folded around the creasing 52, comes to marry the part 77, the hooks 69 coming to cooperate with the holes 54 and the section 50 being detached along the breaking point 51 (see FIG. 10

and figure 11).

  The tool 60 thus furnished is engaged between the body 81 and the flap 84 of the case 70 (see FIG. 13) so that one of the dough pieces 12 is applied against the internal surface of the flap 84 and the other against the ends. partitions 85, the user then presses the pusher 63 so that

the hooks 69 are deleted.

  During the fitting of the contact members 87, the strip 10 is torn off, the dough pieces 12 remaining adherent to the case 70. When the various members 87 are placed, the cover 84 is closed so that the material forming the dough pieces 12 fills all compartments spaces 86

  to ensure a certain seal.

  When a section 50 has been laid, the user presses the lever 29 so that a new section 50 is placed in the V 40b and can thus be removed

by tool 60.

  Of course, the invention is not limited to

  embodiment which has just been described and represented.

  We can make many modifications in detail

  without departing from the scope of the invention.
