A flexible coupling for pipework comprises a rigid sleeve of circular section engaged coaxially around the ends of pipes to be coupled together and connected to each of said ends in sealed manner by means of respective annular gaskets of flexible and resilient material received coaxially in each of the annular gaps between the ends of the pipe and the ends of the sleeve. The sleeve is made up of an assembly of three rigid tubes in alignment along the same longitudinal axis and assembled together in sealed manner by connection means comprising annular gaskets analogous to the above-mentioned annular gaskets and by two sets of laminated blocks which hold the tubes rigidly in alignment on the longitudinal axis, but which allow limited amplitude mutual displacements thereof with resilient return along the axis and around the axis.
