Abstract:
1. In combination with a lamp having a polygonal-section plug part extending along an axis and having at least one radially outwardly directed face formed with a radially outwardly projecting retaining bump, a socket comprising: a core body formed with a polygonal-section socket hole complementary to the plug part and into which the plug part can be fitted axially in an installed position and that substantially completely prevents angular displacement of the plug part relative to the core body in the installed position; and a sleeve surrounding the core body and angularly displaceable relative thereto between a freeing end position and a blocking end position, the sleeve being formed with a radially inwardly projecting retaining formation that, in the installed position of the plug part, is angularly offset from the bump in the freeing position and that operatively engages and blocks axial displacement of the bump in the blocking position, whereby, in the installed position of the plug part, the lamp can be withdrawn from the socket in the freeing position of the sleeve but is locked and cannot be withdrawn in the blocking position of the sleeve.
