A restraining pipe coupling for a pipe to be restrained, comprising: a coupling sleeve for receiving an end of the pipe and comprising a coupling sleeve tab which protrudes radially and has an annular abutment surface; a sealing ring for sealing between the annular abutment surface of the coupling sleeve and the pipe; a plurality of coupling sectors (11, 31) which are shaped as circumferential annular sectors and radially displaceable towards the pipe by circumferentially tightening between consecutive coupling sectors; a plurality of restraining members (13, 14, 40, 42), each restraining member being formed by a plurality of restraining member elements (13, 14, 40, 42) comprising a gripping surface for restraining the pipe from being pulled from the coupling; wherein each of the coupling sectors (11, 31) comprises a first recess arranged towards the pipe for slidably receiving the coupling sleeve tab and the sealing ring; each of the coupling sectors (11, 31) comprises a second recess arranged towards the pipe for receiving one or more restraining members; each restraining member element (13, 14, 40, 42) is wedge-shaped by comprising a surface which is inclined towards a longitudinal central axis of the pipe, such that the inclined surfaces of the coupling restraining member elements form a combined frustoconical restraining surface which tapers radially inwards away from the coupling sleeve; and the second recess comprises an inclined recess surface, such that the inclined recess surfaces of the coupling sectors (13, 14, 40, 42) form a combined frustoconical abutment surface for facing against the combined frustoconical restraining surface; wherein when the coupling sectors (13, 14, 40, 42) are radially displaced towards the pipe by circumferentially tightening between consecutive coupling sectors, the sealing ring is compressed against the pipe and the annular abutment surface of the coupling sleeve; and when the pipe is pulled from the coupling, the restraining member elements, by the mutual sliding of the frustoconical surfaces, are tightened together and against the pipe, characterised in that each circumferential sector comprises a spring-like element behind a semi-annular restraining member, arranged for allowing some tolerances on the restraining members so that small axial misalignments can be absorbed. a coupling sleeve for receiving an end of the pipe and comprising a coupling sleeve tab which protrudes radially and has an annular abutment surface; a sealing ring for sealing between the annular abutment surface of the coupling sleeve and the pipe; a plurality of coupling sectors (11, 31) which are shaped as circumferential annular sectors and radially displaceable towards the pipe by circumferentially tightening between consecutive coupling sectors; a plurality of restraining members (13, 14, 40, 42), each restraining member being formed by a plurality of restraining member elements (13, 14, 40, 42) comprising a gripping surface for restraining the pipe from being pulled from the coupling; wherein each of the coupling sectors (11, 31) comprises a first recess arranged towards the pipe for slidably receiving the coupling sleeve tab and the sealing ring; each of the coupling sectors (11, 31) comprises a second recess arranged towards the pipe for receiving one or more restraining members; each restraining member element (13, 14, 40, 42) is wedge-shaped by comprising a surface which is inclined towards a longitudinal central axis of the pipe, such that the inclined surfaces of the coupling restraining member elements form a combined frustoconical restraining surface which tapers radially inwards away from the coupling sleeve; and the second recess comprises an inclined recess surface, such that the inclined recess surfaces of the coupling sectors (13, 14, 40, 42) form a combined frustoconical abutment surface for facing against the combined frustoconical restraining surface; wherein when the coupling sectors (13, 14, 40, 42) are radially displaced towards the pipe by circumferentially tightening between consecutive coupling sectors, the sealing ring is compressed against the pipe and the annular abutment surface of the coupling sleeve; and when the pipe is pulled from the coupling, the restraining member elements, by the mutual sliding of the frustoconical surfaces, are tightened together and against the pipe, characterised in that each circumferential sector comprises a spring-like element behind a semi-annular restraining member, arranged for allowing some tolerances on the restraining members so that small axial misalignments can be absorbed.
