The invention concerns a connection element designed to connect two structural components, in particular a support girder and a frame girder, so that they can be detached again. The connection element is designed to be inserted in the hollow-section frame girder so that it remains fixed in place. It has at least one movable securing element which is disposed in a housing and which can be displaced in the direction of the longitudinal axis of the connection element by means of an eccentric pin which is rotatably mounted in an aperture in the housing and which passes through the securing element, thus bringing a coupling hook forming part of the securing element and projecting out of the end of the housing into engagement with a longitudinal groove undercut in the support girder. The eccentric pin is designed to be pushed into the housing against the force of a spring and locked in a cross-bore in the frame girder. In order to ensure that the securing element operates faultlessly in any position, the invention calls for the floor of the housing to have a recess which is disposed eccentrically with respect to the mounting aperture and with which a cam disc on the eccentric pin is brought into engagement at least when the securing element is in its extended position.
