Abstract: A connector for connecting a support and a frame disposed so as to be perpendicular thereto. The connector has at least one bolt or hook having an undercut which is configured for engaging in a keyhole-shaped through opening on the frame or support. The dimensions of a front end portion of the bolt or hook are adapted to a wider portion of the through opening, and the dimensions of the undercut are adapted to a narrower portion of the through opening. A housing of the connector is capable of being fixed to the end side of the support or frame, and the at least one bolt or hook is disposed so as to be displaceable parallel with a longitudinal direction of the support or frame into the housing of the connector.
