The clamp fitting for a pipe, in particular, a plastic pipe or a plastic-metal composite pipe, is provided with a fitting body having a support sleeve onto which one end of a pipe to be connected can be pushed. Clamp fitting further comprises a clamping sleeve having a wall that has a slot running between its axial ends that is delimited by opposing flanks of the wall and is expandable, wherein clamping sleeve surrounds support sleeve and end of the pipe to be connected in the state when it has been pushed onto the support sleeve. To maintain the expanded state of clamping sleeve, a removable spacer, against which flanks of the wall that delimit slot of the expanded clamping sleeve are supported, is arranged in slot.

Clamp fitting for a pipe

The press fitting for a pipe is provided with a fitting element which comprises a supporting element onto which a pipe to be connected can be pushed. Furthermore, the press fitting comprises a compression sleeve which has on its circumferential surface a compression region corresponding to the region a pressing tool acts on the compression sleeve during the compression thereof. A plastic ring is situated on the outside of the compression sleeve and is secured thereon against movements in the axial direction of the compression sleeve wherein the plastic ring has at least one axial projection which extends right into the compression region of the compression sleeve and which can be destroyed when the pressing tool acts on the compression sleeve and/or is secured so that it can be separated from the plastic ring.
