Cable conveyor belt joining device provided with cable locking elements

A joining device for at least one conveyor belt of the type extending along a longitudinal axis and comprising a body made of flexible material inside which a reinforcement comprising reinforcing cables extending at least in part axially is accommodated, the joining device being intended to connect at least a first and a second end portion of the conveyor belt,

• wherein
• the joining device comprises at least one assembly of at least two locking elements connected to each other by assembly means comprising at least one connecting cable, the assembly being intended to be attached to the first end portion and the second end portion of the conveyor belt, so as to connect at least some of the reinforcing cables of the first end portion of the conveyor belt to at least some of the reinforcing cables of the second end portion of the conveyor belt, and
• each locking element comprises at least two opposite supports configured to enclose at least a portion of an associated cable among the reinforcing cables and the connecting cable, the supports each having at least one groove together defining at least a part of a through-cavity for receiving at least the portion of the associated cable passing through the locking element between an entrance opening and an exit opening aligned in accordance with a reference axis, the cavity having a widened intermediate part between entrance and exit opening portions, radially widened relative to the entrance opening portion and the exit opening portion, and the locking element comprises at least one anchor configured to at least partially occupy a portion of the widened intermediate part of the cavity located in alignment with the entrance and exit openings, so as to locally create a radial deformation of the cross-section of the portion of the associated cable.
