Abstract
A quick coupling (1) comprising a sleeve-shaped coupling body (3) with a receiving opening (4) to receive one end (5) of a pipe (2), a retaining element (7) to hold the end (5) of the pipe in the coupling body (3), a sealing element (8) to seal the pipe (2) against the coupling body (3) and a securing element (9) to secure the connection between the pipe (2) and the coupling body (3), in conjunction with which reinforcing ribs and locking ribs (23,24) are executed adjacent to the receiving opening (4) on an external surface (21) and an internal surface (22) of the coupling body (3), which ribs extend inwards and outwards in a radial direction and interact with the securing element (9) for the purpose of securing the connection between the pipe (2) and the coupling body (3).
