Abstract: A multipin header connector pin extraction tool having a resilient tool head with pin grasping fingers resiliently held in spaced, pin receiving relationship for receipt of a contact pin to be extracted is attached to an elongate tool shank slidingly received within an elongate bore within an elongate tool handle. A pair of opposed cam surfaces and a plurality of detent ball bearings held in associated bearing access openings are carried by the handle. A locking collar slideably moves between a nonlocking position and, when the tool shank has been moved to pin grasping position and a detent groove has been aligned with the access openings, a locking position. The detent ball bearings are held in locking engagement with the detent groove after the tool handle has been pushed against the tool head which is held against the header to cam the fingers into grasping relationship with the object pin.
