Abstract
The present invention relates to a device for joining together building units, comprising a lock housing (2) positioned in one building unit; a peg (3) positioned in the other building unit and arranged to be inserted into the lock housing, the end of the peg being provided with a flange (8); and a means for locking the peg (3) in the lock housing in the longitudinal direction thereof. In order to prevent the sideward movement of the peg with respect to the lock housing, prior devices comprise a second ring flange attached to the peg at an inlet (9) of the lock housing. The second flange can be omitted, if the bottom plate (1) of the other unit is bent into a collar (10) which surrounds the peg (3) and is attached thereto.
