Abstract

Connection assembly (1) for connecting a first and second pipe end (201, 301) of pipes (200, 300). The pipe ends exhibit outwardly facing pipe locking profiles (203, 303). Locking segments (101) are distributed about the second pipe end (301) and have a connected (103) and a movable portion (105) with segment locking profiles (103a, 105a). The movable portion (105) is pivotable between an inward locking position and an outward free position. Among the pairs of facing locking profiles, comprising a first pair including the segment locking profile (103a) and facing pipe locking profile (303) of the second pipe end, and a second pair, at least one pair exhibits an inclined face (S1, S2, S3) which is misaligned a misalignment distance (M1, M2, M3) with respect to the facing inclined face (P1, P2, P3) of the profile with which it engages.
