A stabbing guide connects to a casing collar during makeup. The stabbing guide has a housing with a lower portion with a cylindrical interi-or and an upper portion with a conical interior. Upper and lower shoulders are located in the cylindrical interior, defining an annular recess between the shoul-ders. Each of the shoulders has an inner diameter smaller than an outer diame-ter of the casing collar. The housing is formed in separate segments and secured around the casing collar by a clamp.
