Abstract: In a cable clamp intended for connecting a cable conductor to a connecting tongue (4) protruding from a flat metal element a stirrup (1) surrounding a U-shaped contact member (2) and a pressure plate (7), and a screw (3) screwed through the crown of the stirrup. There is a boss (6) arranged on the side of the contact member (2) facing the tongue (4) and adapted for accommodation in a hole in the tongue. A U-shaped resilient wire bale (5) has bent ends engaged in holes and recesses (9) in flanges (8) of the contact member (2), closely embracing the tongue (4) such that the bale, when lowered into a position along the tongue, will coact with the boss (6) and lock the contact member to the tongue, and, when raised to a position at right angles to the tongue, will allow the contact member to be released from the tongue.
