PURPOSE: A socket for coupling spiral pipes is provided to improve cohesive force by uniformly pressing the outer side of spiral pipes and to be easily manufactured by uniformly cutting the spiral pipes. CONSTITUTION: A socket for coupling spiral pipes comprises C-shaped coupling members(50,50a), rubber packings(20,20a), and L-shaped fixing brackets(60,60a). First coupling grooves(51,52) corresponding to second coupling grooves(11,11a) of spiral pipes are formed in the inner sides of the coupling members. The rubber packings are fitted to the first and second coupling grooves of the coupling members. The L-shaped fixing brackets are fixed to the front ends of the coupling members using fixing bolts(70).
