The present invention is directed to a ball joint connector for connecting an elongated element to a ball pin, comprising a socket having a cylindrical cavity for receiving a ball of a ball pin with an opening at one end and a dome-shaped end wall at the opposite end, and a clip disposed at least partially within the cavity and dimensioned to encompass more than the upper hemisphere of the ball, said clip being moveable between a locking position and a retracted assembly/disassembly position characterized in that the clip is arranged to extend, in its locking position, in abutment with the surface of a ball received in the cavity on opposing sides of the ball on each side over a portion of the upper hemisphere and with its lower end portion over an adjoining surface portion of the lower hemisphere. |

1. A ball joint connector for connecting an elongated element to a ball pin (2), comprising,
a socket (10) having a cylindrical cavity (12) for receiving a ball of the ball pin with an opening (14) at one end and a dome-shaped end wall (11) at the opposite end, the socket being adapted to be connectable to the elongated element; and a clip (30) disposed at least partially within the cavity and dimensioned to encompass, when the ball is received in the cavity, more than an upper hemisphere of the ball which is opposite to a lower hemisphere on which a pin of the ball pin is coaxially carried, said clip being moveable between a locking position, in which it extends with two opposite end portions into the lower hemisphere of the ball to be in abutment with surface portions in the lower hemisphere to hold the ball secured in the cavity, and a retracted assembly position in which its opposite end portions allow the ball to pass for one of an insertion to or removal from the cavity, characterized in that the clip (30) is arranged to extend, in the locking position, in abutment with a surface of the ball received in the cavity on opposing sides of the ball on each side over a portion of the upper hemisphere and with its opposite end portion over an adjoining surface portion of the lower hemisphere of the ball, and the clip (30) is received in grooves (40) formed in an inner wall of the cavity extending in a symmetrical manner on opposite side regions of the cavity from a first end close to the opening of the cavity to a second end in the dome-shaped end wall; and wherein a depth of each groove is increasing starting from a first end to form a flaring groove bottom (42) adapted to support the clip end portion in the locking position to keep the ball in the cavity, wherein the increasing depth of the groove is arranged such that the opposite end portions of the clip are, in the assembly position, free to be moved radially outwardly into a region (44) of increased depth of the groove to allow the ball to pass by the opposite end portions of the clip. |
