A tension ring assembly for securing around a pipe, the assembly comprising a tension ring, at least one lifting lug removably secured to the tension ring, so that the tension ring, and a pipe around which the tension ring has been secured, can be upwardly tensioned, the tension ring comprising: - a plurality of collar segments (14, 16) configured to be assembled into a ring, said assembled ring of collar segments extending around a ring axis and having in a radially outer face of said assembled ring at least one recess to which said lifting lug is secured; - at least one collar segment connection member (36, 38) for connecting the collar segments together to form said assembled ring when said collar segments are assembled around said pipe; and - a plurality of slip segments adapted to fit between the collar segments (14, 16) and the pipe, the slip segments having radially inner faces for making direct contact with an outer surface of the pipe, the collar segments and the slip segments when assembled having inclined contacting surfaces (24, 25) such that an inner diameter across said assembled ring, between the inner faces of the slip segments, varies as the slip segments move in a substantially axial direction up and down inside said assembled collar segments; - characterised in that the tension ring assembly further comprises at least one securing pin for removably securing said lifting lug to the tension ring, and said collar segment has for said recess at least one bore into which a corresponding securing pin may, in use, be removeably inserted, said bore intersecting said recess such that a portion of said inserted pin protrudes inside said recess, and said lifting lug comprises: - a main body and at least one tongue, said tongue extending away from said main body and being configured to slot in a substantially radial direction into said recess in order to position said main body on said radially outer face, said tongue having a keyway for engaging with said protruding portion of said inserted pin, the configuration of said tongue, recess and bore being such that the keyway comes into alignment with said bore when said tongue is slotted into said recess so that when said pin is inserted into said bore, the protruding portion of said inserted pin engages with the keyway to secure said lug in position, and so that when the pin is removed from said bore, said protruding portion of said inserted pin disengages from the keyway to free said lug for removal from said collar segment (14, 16); - wherein said bore is an axially extending bore that partially intersects said recess and said keyway extends axially to align with said bore where said bore partially intersects said recess, whereby the protruding portion of said inserted pin is a portion in cross-section of said pin. - a plurality of collar segments (14, 16) configured to be assembled into a ring, said assembled ring of collar segments extending around a ring axis and having in a radially outer face of said assembled ring at least one recess to which said lifting lug is secured; - at least one collar segment connection member (36, 38) for connecting the collar segments together to form said assembled ring when said collar segments are assembled around said pipe; and - a plurality of slip segments adapted to fit between the collar segments (14, 16) and the pipe, the slip segments having radially inner faces for making direct contact with an outer surface of the pipe, the collar segments and the slip segments when assembled having inclined contacting surfaces (24, 25) such that an inner diameter across said assembled ring, between the inner faces of the slip segments, varies as the slip segments move in a substantially axial direction up and down inside said assembled collar segments; - characterised in that the tension ring assembly further comprises at least one securing pin for removably securing said lifting lug to the tension ring, and said collar segment has for said recess at least one bore into which a corresponding securing pin may, in use, be removeably inserted, said bore intersecting said recess such that a portion of said inserted pin protrudes inside said recess, and said lifting lug comprises: - a main body and at least one tongue, said tongue extending away from said main body and being configured to slot in a substantially radial direction into said recess in order to position said main body on said radially outer face, said tongue having a keyway for engaging with said protruding portion of said inserted pin, the configuration of said tongue, recess and bore being such that the keyway comes into alignment with said bore when said tongue is slotted into said recess so that when said pin is inserted into said bore, the protruding portion of said inserted pin engages with the keyway to secure said lug in position, and so that when the pin is removed from said bore, said protruding portion of said inserted pin disengages from the keyway to free said lug for removal from said collar segment (14, 16); - wherein said bore is an axially extending bore that partially intersects said recess and said keyway extends axially to align with said bore where said bore partially intersects said recess, whereby the protruding portion of said inserted pin is a portion in cross-section of said pin.
