Abstract
The device comprises a vertical shaft (36) movable along its axis under the action of a fluid pressure difference and having means for supporting at least one head (28) of the cluster and a first resilient finger (42) for securing and retaining the head on the support means. It comprises a high position securing mechanism carried by a fixed tube (20) for guiding the cluster and having at least one resilient finger for securing the head and retaining the head against the action of gravity and a vertically movable bolt urged resiliently to a position in which it prevents disengagement of a second resilient finger and cooperating with a mechanism controlling a second cluster so as to be brought into a position in which it releases the second resilient finger when the second cluster passes beyond the highest position assumed during normal operation.
