ABSTRACT OF THE DISCLOSURE: In a device and method for retaining a linearly movable element in a nuclear reactor, the coupling device comprises, for each shaft: a base fixed to the top part of the reactor internals and coaxial with a shaft guide tube; several grippers or catches spaced apart about the axis of the base and mounted for pivotal movement about a horizontal axis towards a position in engagement with a portion, having circumferential grooves, of the shaft contained in the tube and from engagement; a slide movable axially on the base towards a top position where it causes engagement of the catches in a groove of the rod and from this position; and springs bearing on the base and tending to engage the catches on the shaft. The slide is dimensioned so as to be held by the corresponding sleeve projecting through the reactor vessel cover in a position sufficiently distant from the low position for the catches to be released, whatever the temperature in the reactor.
