1. A connection device (1) for connecting a pipe (100) having an outer peripheral projection (110) arranged in a longitudinal portion (120) thereof, the connection device (1) comprising:
a connection part (10) with a receptacle (11) for inserting therein the longitudinal portion (120) of the pipe (100) with the outer peripheral projection (110),
wherein the receptacle (11) has a central axis (13) which extends in an insertion direction (E) and is peripherally delimited by a peripheral wall (15) which extends around the central axis (13),
wherein the receptacle (11) also has a base surface (16.1), which is arranged transversely with respect to the central axis (13), and configured to bring the outer peripheral projection (110) of the pipe (100) or an end (130) of the pipe (100) into contact therewith;
a ring element (30) which is designed to be introduced into a gap (3) between the peripheral wall (15) of the receptacle (11) and the pipe (100) in the receptacle (11) in such a way that an axial end (31) of the ring element (30) acts as a block for the outer peripheral projection (110) in order to secure the pipe (100) against moving out of the receptacle (11); and
a securing part (50) which is assigned to the connection part (10) and has a material portion (51),
wherein the material portion (51) comprises or consists of a deformable material and is designed to be brought into a blocking position by deformation in order to form a block against the ring element (30) moving out of the receptacle (10),
wherein the connection part (10) and the securing part (50) are one piece.
