Abstract: Disclosed is a watch band end attachment adapted to be releasably and adjustably mounted between the spaced lugs of a watch. The end attachment of the invention typically includes a housing, one end of which fits between the spaced lugs and the other end of which is connected to the watch band, and levers on opposite sides of the housing with a sliding member therebetween. The levers have lug-engaging ends disposed in the first end portion of the housing and pivot ends in the second end portion. Cam surfaces of the levers coact with cam-engaging surfaces of the sliding member as the latter is translated from the pivotal ends toward the lug-engaging ends of the levers to cause the lug-engaging ends to pivot and extend through the side apertures in the housing and engage the lugs of the watch. Reverse movement of the sliding member disengages the end attachment from the watch. Accidental disengagement is prevented by locking means typically in the form of a spring associated with the levers or sliding member.
