Battery clamp

A battery clamp connection to a battery contact, said battery clamp comprising:

• a connecting lug;
• a contact ring provided with a slot so as to form two opposite clamping ends;
• a spring for engaging said clamping ends of said contact ring;
• and
• a blocking wedge, which can be shifted between a contact position in which it releases said clamping ends such that said spring can pull said clamping ends together,
• wherein the clamp may be mounted by spreading the clamping ends of said contact ring such that said battery clamp can be placed on said battery contact,
• wherein the clamp may be removed by spreading the clamping ends of said contact ring further apart than in said mounting position such that said battery clamp can be pulled off from said battery contact,
• wherein each clamping end is provided with a bent-off lug which comprises a first slope,
• wherein said blocking wedge is arranged between said lugs of said clamping ends,
• wherein each lug is provided with an arresting edge, and
• wherein each lug is additionally provided with a second slope which, as seen from said first slope, lies behind said arresting edge, a minimal distance between said two opposite second slopes being smaller than a distance between said two opposite arresting edges.
