A pipe repair kit for repairing a pipe or pipe joint, the kit comprising: a segmented housing for receiving the pipe or pipe joint to be repaired, the housing comprising a plurality of segments (12a, 12b, 12c) for placement around the pipe or pipe joint; securement means for flexibly securing the segments (12a, 12b, 12c) of the housing together around the pipe or pipe joint; and tensioning means for surrounding the secured segmented housing and clamping the segments (12a, 12b, 12c)thereof into clamping and sealing relationship with the pipe or pipe joint, characterised in that: the segments (12a, 12b, 12c) are of substantially equal radial width and circumferential length; the segments (12a, 12b, 12c) are each articulated with respect to an adjacent segment via their respective securement means; and by the housing comprising an odd number of segments (12a, 12b, 12c), such that on one diametrical side of the pipe or pipe joint, the joint or interface between any given two adjacent segments (12a, 12b) is not directly diametrically opposite a like joint or interface between adjacent segments (12b, 12c) on the opposite side of the pipe or pipe joint, and/or such that the said joint or interface between any given two adjacent segments (12a, 12b) is directly diametrically opposite a substantially central- or intermediate- or mid-portion of one segment only on the opposite side of the pipe or pipe joint. a segmented housing for receiving the pipe or pipe joint to be repaired, the housing comprising a plurality of segments (12a, 12b, 12c) for placement around the pipe or pipe joint; securement means for flexibly securing the segments (12a, 12b, 12c) of the housing together around the pipe or pipe joint; and tensioning means for surrounding the secured segmented housing and clamping the segments (12a, 12b, 12c)thereof into clamping and sealing relationship with the pipe or pipe joint, characterised in that: the segments (12a, 12b, 12c) are of substantially equal radial width and circumferential length; the segments (12a, 12b, 12c) are each articulated with respect to an adjacent segment via their respective securement means; and by the housing comprising an odd number of segments (12a, 12b, 12c), such that on one diametrical side of the pipe or pipe joint, the joint or interface between any given two adjacent segments (12a, 12b) is not directly diametrically opposite a like joint or interface between adjacent segments (12b, 12c) on the opposite side of the pipe or pipe joint, and/or such that the said joint or interface between any given two adjacent segments (12a, 12b) is directly diametrically opposite a substantially central- or intermediate- or mid-portion of one segment only on the opposite side of the pipe or pipe joint. the segments (12a, 12b, 12c) are of substantially equal radial width and circumferential length; the segments (12a, 12b, 12c) are each articulated with respect to an adjacent segment via their respective securement means; and by the housing comprising an odd number of segments (12a, 12b, 12c), such that on one diametrical side of the pipe or pipe joint, the joint or interface between any given two adjacent segments (12a, 12b) is not directly diametrically opposite a like joint or interface between adjacent segments (12b, 12c) on the opposite side of the pipe or pipe joint, and/or such that the said joint or interface between any given two adjacent segments (12a, 12b) is directly diametrically opposite a substantially central- or intermediate- or mid-portion of one segment only on the opposite side of the pipe or pipe joint.
