Abstract:
1. A connecting device for a pipe, comprising: a coupling body having an inner wall, a stop, a substantially cylindrical recess having an inlet, and a sloped surface extending radially inwardly from said inner wall in a direction toward said inlet; and a clamping collar having at an inner end thereof at least one radially displaceable arresting tongue, with said clamping collar being receivable within said substantially cylindrical recess and for, when received within said substantially cylindrical recess at an axially inner starting position, slidably receiving a pipe until one end of the pipe abuts said stop, such that when the pipe is slid away from said stop in a direction toward said inlet, along with said clamping collar being slid in the direction toward said inlet from the axially inner starting position to an axially outer arresting position, an outer side of said at least one radially displaceable arresting tongue cooperates with said sloped surface so as to be displaced radially into engagement with an outer wall surface of the pipe, wherein said clamping collar is divided into an axially inner function section and an axially outer actuation section, with a seal positioned between facing front sides of said axially inner function section and said axially outer actuation section, said seal for sealing against said inner wall and against the outer wall surface of the pipe, and with said axially inner function section having said at least one radially displaceable arresting tongue.
