FIELD: splicing insulated conductors for communication facilities. SUBSTANCE: spiral spring of splicing head is loosely mounted on limiting rod and is free to displace in axial direction. Conductors of any diameter can be locked in position with aid of head because initial point of spring and its position on rod can be easily chosen and spring turns can secure conductors of any diameter. Moreover, conductors can be secured simultaneously at both ends of spring. EFFECT: enlarged functional capabilities. 12 cl, 5 dwg
