Abstract: A cable assembly (100) having a first cable (20) having a first conductor (22), a second cable (40) having a second conductor (42) and an electrically conducting joining element (60). The joining element (60) has a first opening (61) and a second opening (63). The cable assembly (100) comprises a number of canted coil springs (70). A terminal portion of the first conductor (22) is secured to the first opening (61) by means of a first canted coil spring (70). A terminal portion of the second conductor (42) is secured to the second opening (63) by means of a second canted coiled spring (70).
