Connection assembly

A connection assembly adapted to connect a first pipe end and a second pipe end of respective first and second pipes in a position where the first and second pipe ends are coaxially arranged and abutting each other, wherein the first and second pipe ends exhibit radially outwardly facing pipe locking profiles, and wherein the connection assembly comprises:

• a plurality of locking segments which locking segments are distributed about a perimeter of the second pipe end and which locking segments have a connected portion and a movable portion, the connected portion and the movable portion each have segment locking profiles facing the pipe locking profiles, and wherein the movable portion is radially pivotable, between an inwardly pivoted locking position and an outwardly pivoted free position, about a pivot section;
• a retainer sleeve extending about a circumference of the second pipe and having an axially protruding retainer shoulder under which retainer shoulder a part of the connected portion of the plurality of locking segments is arranged and under which retainer shoulder the pivot section is located;
• a securing sleeve extending about a circumference of the first pipe and having an axially protruding securing shoulder under which securing shoulder a part of the movable portion of the plurality of locking segments are arranged when the plurality of locking segments are in the locking position;
• a first pair of locking profiles including the segment locking profile of the connected portion and facing pipe locking profile of the second pipe end, and
• a second pair of locking profiles including the segment locking profile of the movable portion and the facing pipe locking profile of the first pipe end, at least one pair exhibits an inclined face which is misaligned a misalignment distance with respect to the facing inclined face of the profile with which it engages, which brings about tensile stress in the axial direction in the locking segments when they are in the locking position;
• and wherein
• the locking segments comprise radially outwardly facing actuation faces and are adapted to be pivoted inwards by means of a tool by engagement of said actuation faces;
• wherein the locking segments remain in the locked position when the tool is removed, as the securing sleeve secures the locking segments in the locking position.
