A device for reducing migration of a pin of an intramedullary fixation device, especially to reduce migration of a clavicle pin introduced in the medually canal of the clavicle to fix a fractured clavicle bone. A clavicle nail (50) with a curved tip is inserted within the meduallary canal of the clavicle. The back end of the nail that extends out of the clavicle is provided with indentations or grooves. The back end of the nail is received in a hollow cavity of a cap (10), which locks onto the indentations or grooves of the nail. A screw (80) is placed through an eyelet of the cap and turned into the clavicle to secure the cap to the clavicle. As a result, the nail is fixed within the medullary canal and undesirable migration of the pin within the meduallary canal is reduced.
