The invention relates to a component which is replaceable be remote control and which in the installed condition is releasably secured to a stationary component. In the remote handling art, there is a need to be able to exchange components, which are replaceable under remote control, safely, rapidly and reliably with remote handling equipment which is of maximum simplicity and with a small number of remote handling steps. For that purpose, at least two locking devices are provided laterally on the replaceable component. Each locking device has a perpendicularly mounted carrier on which a locking claw is pivotally mounted. The locking claws are provided with guide slots. Lateral guide trunnions of an entrainment member are provided with a threaded bore and engage the guide slots so that the entrainment member can be moved vertically by an elongated threaded actuating member which is fixed axially in position so that it remains at the same elevation. The locking claw can thus engage the stationary component from below.
