Abstract
A movable connection part of an extrusion head is integral with a fixed connection part in a connection unit wherein each moveable connection part and fixed connection part includes elastically deformable tubular members inserted into bores. Jaws are connected to a knuckle-jointed system, which when actuated by a single jack in one direction, will move the jaws away from one another to free the connection parts and when moved by the single jack in an opposite direction, will press the connection parts against one another by acting upon bevels.
