Title: Joining and connecting element for corrugated pipes

Abstract: The connecting component or the connecting fitting (1) comprises at least one locking element which can be shifted-in and shifted-out radially to the longitudinal axis (14) of the fitting (1). The locking element is, for example, connected as a wing (7) via a hinge (22) with the fitting (1) or forms an additional element. On the inside face (10) of the locking element (7) are disposed a multiplicity of locking splice-clips (12) which are resilient. When a pipe end is slid into the fitting (1) with the locking elements (7) closed, these locking splice-clips (12) can be deflected. When load is applied against the insertion direction they become clawed in the pipe jacket. This embodiment permits the shifting-in or dosing of the locking elements (7) in a preassembly step and yet ensures a secure connection. The release of the connection through the radial shifting-out of the locking elements (7) is possible at any time.
