Abstract: A support for an elongate element comprises a body portion adapted to restrain a supported elongate element against lateral movement. The body portion has a plurality of partial shells extending therefrom, each partial shell having a cross section substantially conforming to a part of the profile of the elongate element to be supported. Adjacent partial shells extend in opposing lateral directions relative to the longitudinal axis of the support. The support may be a split cylinder having a helical groove extending longitudinally of the support, the width of the groove 16 being at least equal to the diameter of the elongate element to be supported.
