Abstract

A pipe connecting system for first and second pipe pieces extending along a common longitudinal axis includes a clamp. The pipe pieces each have first end and first clamping surfaces. The clamp has first and second contact surfaces lying against respective clamping surfaces to prevent the clamping surfaces from moving away from one another, while leaving a space between the first and second end surfaces. A retaining ring has a sealing connection attachment to the second pipe piece, and on which a sealing ring is mounted, the sealing ring lying against a circumferential first sealing surface of the first pipe piece. An interior of the first and second pipe pieces between the two pipe pieces is sealed against the surrounding environment by the sealing connection. The two pipe pieces can move towards one another without the first sealing ring moving out of contact with the first sealing surface.
