CONNECTION ASSEMBLY FOR THE CONNECTING OF A CYLINDRICAL BRANCH OF A PLASTIC PIPE, AND METHOD FOR THE ATTACHING OF A CYLINDRICAL BRANCH TO A PLASTIC PIPE

摘要

Connection assembly (20) for the connecting of a cylindrical branch of a plastic pipe, which connection assembly comprises: - an insert pipe (21) which is to be inserted in the opening in the wall of the plastic pipe, which insert pipe has a flange (22) and is displaceable with respect to the annular wall of the opening in the pipe between a first position and a second position in a direction which is substantially perpendicular to the axial direction of the pipe, - a support ring (28) which has, when mounted, a substantially fixed position with respect to the annular wall of the opening in the plastic pipe, but which support ring is detached from the insert pipe, - a locking means (35) for the securing- of the insert pipe in the second position. The connection assembly according to the invention also has a deformable blocking ring (25), which blocking ring can assume a stretched and a folded form.
