Abstract: A pipe coupling (100) for receiving, holding and releasing a pipe, comprising a coupling body (110) having a bore (B) with a geometric axis (A) into which a pipe can be inserted in a pipe insertion direction (P); a rotatable sleeve (170) which is arranged at least partially around the coupling body (110) and which is rotatable around the axis of the bore with respect to the coupling body (110); a gripping element (140) configured to engage a surface of the pipe; a pipe release element (160) configured to disengage the gripping element (140) from the surface of the pipe upon axial movement of the pipe release element (160); and a release collar (180) coupled to an end of the rotatable sleeve (170). Axial rotation of the rotatable sleeve (170) in a first direction causes the release collar (180) to move axially from a locked position to an unlocked position and wherein in the unlocked position, the release collar (180) can be moved axially in a pipe insertion direction (P) to cause the pipe release element (160) to disengage the gripping element (140) from the surface of the pipe.
