Quick-made connection for a stud having a shaped outer profile

A quick-made connection for a stud (2;

• 22;
• 52) having a shaped outer profile (3;
• 23;
• 53), comprising a receiving member (4;
• 24;
• 32;
• 42;
• 59) having a bore (5;
• 25;
• 33;
• 43;
• 54) in which the stud (2;
• 22;
• 52) is received;
• and at lest one locking member and formlockingly engageable in the shaped outer profile (3;
• 23;
• 53) of the stud (2;
• 22;
• 52), with the bore (5;
• 25;
• 33;
• 43;
• 52) having at least one section (9;
• 29;
• 34;
• 44;
• 55;
• 56) tapering toward an insertion opening (6;
• 26) of the bore, with the locking member (10;
• 30;
• 36;
• 46;
• 57;
• 58) being formed as a radially elastically expandable ring member held in the bore (5;
• 25;
• 33;
• 43;
• 54) without a possibility of an essential displacement in an insertion direction (I), and being preloaded against an inner wall (7;
• 27) of the bore, and with an inner diameter (w) of the ring member (10;
• 30;
• 36;
• 46;
• 57;
• 58) being smaller than a diameter (d) of the bore (5;
• 25;
• 33;
• 43;
• 54) at an insertion opening (6;
• 26) thereof;
• wherein the ring member (36;
• 46;
• 60) has a separation opening (37) in a circumferential direction;
• wherein the ring member is formed of spring steel;
• and
• wherein the ring member (46;
• 60) forms part of a one-piece elastic shackle having two pairs of shackle member arranged diametrically opposite each other, with the shackle members projecting axially from the ring member and extending parallel to each other, the shackle members having outwardly bent, hooked free ends and providing for support of the ring member on the receiving member in the axial direction.
