Abstract (en)
[origin: WO2022003413A1] The present disclosure belongs to the field of restraining connections for pipe couplings. The present subject-matter discloses a pipe coupling to apply in structures for laying and restraining pipes with a circular cross section. In particular, the pipe coupling of the present disclosure may be used to establish longitudinally sealed and force- locked connections with PVC or PE pipes. It comprises a coupling sleeve (3) for receiving an end of the pipe (4) to be restrained and having a first annular abutment surface; a clamping ring (2) having a second annular abutment surface, a pipe collar formed by wedge- shaped segments (15) comprising a support body (10) and a gripper (11) arranged to be placed between the pipe and the support body (10), an annular seal (13) for sealing the sleeve (3) to the pipe (4),
