ABSTRACT OF THE DISCLOSURE Equipment is disclosed for closing conduits and comprises a closing lid having two circular disks with a peripheral sealing ring of resilient material. A tightening device connects the two disks at the center thereof causing during tightening the compression of the sealing ring radially outwardly. The tightening device is of very stable construction conferring to the disks a parallel movement without mutual rotation. The equipment further comprises a mounting device having three parts which are mobile in relation to each other, namely an attachment yoke, a main clamp and a support plate. With the aid of a cog gear and racks, rotary movements are transformed into either a clamping movement between the closing lid and the support plate or a pulling movement between the closing lid and the main clamp.
