MODULAR CONSTRUCTION SYSTEM CONSTRUCTION ELEMENT COUPLING ELEMENT END ELEMENT AND TOOL FOR USE IN SUCH A CONSTRUCTION SYSTEM

摘要

The invention relates to a modular construction system comprising at least two construction elements (20) and a coupling element (1) wherein : the coupling element (1) comprises a body (2) with two surfaces which are each provided with coupling means wherein the coupling means of at least one surface comprise a ring of resiliently pivotable lips (4) provided with locking protrusions; at least one of the two construction elements comprises an opening (22) for receiving the lips of the coupling element; the lips are adapted to displace inward in order to release the connection between the coupling element and the construction element; and the plate like body of the coupling element comprises an opening (6) which is provided with resiliently pivotable tongues (7) extending radially inward which are connected to the lips (4) wherein the tongues are displaced out of the plane of the plate like body by a force being exerted thereon such that due to displacement of the tongues the lips are displaced inward.
