Wire connection sleeve, a wire connection sleeve producing method, a repair wire pre-connected with a wire connection sleeve by crimping and a wire connecting method
A wire connection sleeve includes a pipe-like outer tube (20) and an inner tube (30) inserted inside this outer tube (20). The inner tube (30) is formed by winding a sheet-like metal material (P) formed with projections or recesses into a tubular shape with both ends being open, and a longitudinal middle part of this inner tube (30) serves as an inner-tube small-diameter portion (32) which is so squashed or deformed that the opening size thereof is smaller than those of the opposite longitudinal ends.
