Abstract: A modular raceway for confinement of electrical cables and the like, comprising a plurality of modular elements which can be coupled together by way of interlocking elements. Each of the modular elements comprises a body with radially arranged arms which are uniformly distributed along a circumference in order to form raceway portions for cable passage and end with protrusions which protrude along a circumferential portion. Angular positioning elements are further provided for the angular offset, about the longitudinal axis, of the modular elements arranged side by side.
