Label-holder element for electric wires

1. A label-holder element for coupling to an electrical wire and extending along a lengthwise longitudinal direction (X-X), the label holder comprising:

a body extending in the longitudinal direction (X-X) parallel in use to the longitudinal direction of the electrical wire, a transverse widthwise direction (Y-Y) and a vertical thickness direction (Z-Z), wherein the body comprises:

a front face provided with a seat for a label, side faces oppositely oriented in the transverse direction (Y-Y), and a rear face oppositely oriented to the front face in the vertical direction (Z-Z);

at least one pair ( 440 ; 450 ) of teeth ( 441 ; 541 ) extending outwardly from the rear face ( 410 c ; 510 c ) in the vertical direction (Z-Z) for coupling with the electrical wire ( 200 ), wherein the teeth of one pair extend outwards in the vertical direction (Z-Z) from the rear surface on opposite sides of a longitudinal-vertical plane orthogonal to the rear surface ( 410 c ; 510 c ), each tooth of the at least one pair of teeth having a free end directed towards the free end of the other tooth in the transverse direction, and the teeth of the at least one pair of teeth arranged staggered in the longitudinal direction for mounting on the electrical wire, and

wherein the seat has a top edge and a bottom edge which extend in the transverse direction, are arranged opposite each other in the longitudinal direction and are formed so as to engage and retain the label, and

wherein label-engaging means are formed in a manner of a respective tooth along each of the top edge and the bottom edge, each tooth forming a corresponding undercut towards an inside of the seat and being, in use, extended along a direction transverse to the wire, whereby the seat directly receives the label from either direction along the transverse direction (Y-Y) and/or frontally along the vertical direction (Z-Z) and the label is retained between each undercut.

2. The element as claimed in claim 1 , wherein each tooth of the seat extends over the entire width of the seat in the transverse direction.

3. The element as claimed in claim 1 , wherein oppositely arranged teeth of the seat have an edge which is directed towards the inside of the said seat and is rounded.

4. The element as claimed in claim 1 , wherein the rear face of the body is bounded by opposite transverse edges and wherein at least one pair of teeth extends outwards in the vertical thickness direction from opposite transverse edges of the rear face of the body.

5. The element as claimed in claim 4 , wherein the teeth of the pair are elastically deformable in the transverse direction.

6. The element as claimed in claim 1 , wherein the teeth of the pair have a respective chamfered free end.

7. The element as claimed in claim 1 , comprising a longitudinal rib which extends in the longitudinal direction for connecting together the free ends of the teeth of a pair and with them defines an open space in the longitudinal direction for allowing mounting of the label-holder element on a wire or, vice versa, insertion of the wire in the label-holder element.

8. The element as claimed in claim 7 , comprising at least two pairs of teeth for coupling with a wire, which are spaced from each other in the longitudinal direction, said longitudinal rib connecting the free ends of all the coupling teeth.

9. The element as claimed in claim 1 , wherein the seat has lateral flanks open in the transverse direction for inserting the label from one side or the other side in the same transverse direction.

10. The element as claimed in claim 1 , comprising at least one relief extending in the vertical direction on the front face of the seat.

11. The element as claimed in claim 10 , wherein said at least one relief is arranged in a central position with respect to the transverse extension of the seat.

12. The element as claimed in claim 1 , wherein the front face of the seat comprises a depression.
