Abstract: Connector assembly for connection to a tubular element. It comprises locking elements (105) with locking profiles (107), movable in locking and unlocking direction. The locking profiles can lock with facing locking profiles (117) of said tubular member (119). The locking elements can be moved in a locking direction as a result of movement of an activation sleeve (101) in a first direction. The locking elements (105) or said activation sleeve (101) comprise guiding elements (109) which are adapted to slide against inclined unlocking guiding surfaces (111) of the activation sleeve (101) or the locking elements. A movement of the activation sleeve in a second direction results in a movement of the locking element in an unlocking direction. The activation sleeve has axially extending activation sleeve protrusions (103) having spaces (102) between them.
