ABSTRACT OF THE INVENTION A device for locking a beam to an upright column. The beam is provided with hooks adapted to be inserted into holes in the upright beam and to be locked by a member which is a part of a spring-activated lock device. The lock device can be extracted and moved to a position in which a first stop surface of the device rests on the outside of the beam below the hole. When the beam is being removed, the lock device is moved to a position such that a second stop surface of the lock device upon insertion of the beam into an upright moves the member to a locking position.
