ABSTRACT:
This connection has, on one of two shafts, a hollow socket (1) which is connected to a driving block (16) whose inner surface forms a frustum of a pyramid for receiving a pyramidal head (24) connected to the second shaft. Furthermore, the socket (1) carries retractable pins (6) urged toward the interior by an elastic system (12, 8) but retained in an outer position by an inner ring (14) which is displaced by the elongated stem of the second shaft when it is fitted in the socket. Notches (30) for receiving the pins (6) are provided on the stem (22) and contribute to the axial locking of the two shafts.
