<p>The device consists of a tubular body (5) with a chamber (51), which permits a seat tube (3) to be pushed into it from below. The outer tube circumference has two side edge sections, which define a slot (57), and the tube has a base (54) on the upper edge (521) of the peripheral tube wall (52). A first gripping element (73,74) moves the edge sections together to clamp the wall around the tube. A frame (61) on the tube base has an upward facing saddle surface (614). A clamp element (62,63) defines a groove to hold the frame (41) of a saddle (4). It has a surface (633), which is in friction contact with the saddle surface. A second gripping element (7) has a shaft (71) extending through the clamp element into the frame.</p> |
