Abstract: An assembly detachably securing an electrical device to a support surface includes a support socket, a first coaxial electrical connector slidable within the support socket via a biasing element, a fitting module connectable to the electrical device has a second co-axial electrical connector for connection with the first coaxial electrical connector. An internal wall of the support socket includes projections, each defining a camming surface and a retaining recess; an external wall of the fitting module comprises externally projecting lugs. The fitting module is secured into the support socket by pushing in the axial direction against the biasing element, such that a lug is directed along a camming surface to thereby move itself or another lug between two projections to enter a retaining recess. The fitting module is released from the support socket by pushing in the axial direction against the biasing element.
