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) projecting from the other building unit; and a locking means (7) by means of which the peg is locked in the lock housing and which comprises two branches (10, 11). After having passed the peg, the branches are turned towards each other by means of a guide surface (12) provided in the lock housing (2). In prior devices the locking means (7) has to be very strong because the contact surface between it and the flange of the peg is small. A large contact surface can be provided between the locking means and the flange of the peg by forming the guide surface into a continuous arched surface (12) which bends the branches sharply towards each other.
