The shear section is configured to engage and shear a section of pipe using induction.

The section of the shank which is connected to the engaging section (3) is designed as a cone extending in the direction of the engaging section (3).

Compressive stresses are introduced into a stretched elastomeric rod, whereby the decreased diameter cross section is maintained by placing a wrapping around and about the stretched rod and adhesively sealing it thereto.
