A pipe repair or joining collar comprising a pair of rigid arcuate casing members (10) which may be drawn together around a damaged pipe or a pair of pipe ends with the interposition of one or more elastomeric arcuate seals (13) and wedges (17) located between the casing members and the seals and adapted to slide inwardly and generally tangentially to force the seals radially inwards to ensure sealing engagement with the pipe or pipe ends, mutually abutting longitudinal resilient sealing strips (16) projecting, at least in part, from opposed faces of the wedges (17) in a manner such that in at least one region of each pair one of the sealing strips is substantially flush with its associated face whilst the other projects from it so that during assembly the projecting strip may ride laterally onto the flush strip to ensure lateral alignment of the casing members. |
