Electrical connection element

Electrical connection element (1) to provide an electrical connection between an electrically conductive element (28) and an electrically conductive plate-like support (7) formed with at least one aperture (45) therein, especially to provide a connection for a protective, optionally grounding conductor,

• said connection element comprising
• a housing (4) of insulating material formed with an essentially flat engagement surface (9), adapted to be placed against the plate-like support (7);
• at least one attachment means (12) carried by said housing and for attaching said housing to said support (7);
• at least one contact element (5) located within said housing (4) for connection to at least one electrical line;
• and
• a metallic strip (28) electrically connected to said contact element (5) within the housing (5), said metallic strip (28) being formed with a bend or crease line (34) separating said strip into a neck portion (31) extending from said housing (4) and a hook portion (36) angled off from said neck portion (31) at an angle with respect to said neck portion in a direction essentially parallel to, or acutely angled with respect to said essentially flat engagement surface (9),
• wherein said neck portion (31) and said hook portion (36) of said metallic strip (28), together with said insulated housing (4), form a lever (48) in which the hook portion, upon insertion thereof through said aperture (45), passes beneath, becomes located under the plate-like, conductive support (7), engages thereagainst at least with an end of the hook portion and is supported by said plate-like support (7), to permit at least part of the neck portion (31) to be passed, by lever action, through said aperture (45).
