Plug-in connector

Disclosed is a plug-in connector comprising a supporting member (1), a fixing part (2) for attaching a conduit free end (3) of a conduit (4) to the supporting member (1), a clamping element (5) which is disposed between the fixing part (2) and the supporting member (1) and can be axially moved relative to the fixing part (2) in the direction of the free end (7) of the fixing part (2), said movement allowing a radially inward-facing wall area (8) of the clamping element (5) to be pressed against the external surface (9) of the conduit (4), and a clawing element (6) that is arranged inside the fixing part and is provided with at least one claw (10) on the radially inward-facing side thereof, said at least one claw (10) being used to engage into or press against the external surface (9) of the conduit (4). The clawing element (6) is connected to the clamping element (5) in such a way that no or only a negligible radial force can be applied to the claw (10) of the clawing element (6) when the inward-facing wall a
