Connecting element Described is a connecting element in order to connect detachably two frame components, in particular a supporting section and a frame section, where the connecting element is mounted permanently in the frame section designed as a hollow section and exhibits in a housing at least one moveable holding element with which the connecting element and thus also the frame section can be connected detachably to the supporting section, and where in the housing an eccentric bolt can be rotated that exhibits at least one eccentric head, an eccentric disk and a trunnion, by means of which the holding element can be moved in the longitudinal direction in the housing, whereby a component belonging to the holding element and projecting from the face of the housing can engage with an undercut longitudinal groove of the supporting section, and whereby the eccentric head of the eccentric bolt that can be pressed against the force of a spring into the housing can lock in a bore of the frame section, and with with a safety preventing the axial mobility of the eccentric bolt in slide-in position of the holding element. To provide a snap-in prevention, with which it is guaranteed that the holding element cannot snap off unintentionally from the eccentric disk, it is provided that the safety comprises at least one cam designed at the moveable holding element and at least one recess formed in the housing bottom, where the cam and the recess are arranged and dimensioned in such a manner relative to one another that in the push-out position of the holding element the cam comes to rest opposite the recess in the housing bottom and thus permits the eccentric bolt to be moved axially, but in the push-in position of the holding element is not engaged with the recess and is braced at the housing bottom and, thus, the eccentric bolt is prevented from moving axially.
