Abstract: A watch band is provided which includes a locking connector means and a watch case male lug. The male lug has flat parallel spaced raised surfaces, the female portion of the connector has two spaced top faces which overlie but are closer together than the raised surfaces of the lug and at least one side wall having a lowered segment between two raised segments providing a suitable configuration for passage of a locking member. The locking member has a neck portion for abuttment of the faces of the female member and shoulder portions, the edges of which abut the sidefaces of the raised surfaces of the male lug when the male lug and female portion of the connector are interengaged.

Abstract: The clasp is made up of two main parts - a box-like receptor, and a spring clip inserted into the receptor. The spring clip has a spring finger that has a free end engaging an end wall of the receptor for holding the parts in locked position, and the receptor includes a release member for releasing the spring finger, and thereby releasing the spring clip from locked position and enabling it to be withdrawn. The spring finger has a hump that pushes the release member back to inactive position as the spring finger is being inserted into the receptor, to prevent accidental movement of the spring finger to unlocked position, but the hump acts as a camming surface against which the release member works in the releasing movement.

Abstract: An improved security buckel for a wrist watch metal bracelet is disclosed which utilizes a first and second frame work, one mounted within the other, which are provided with a limited amount of relative sliding movement. A spur of the first frame work is in engagement with or is disengaged from a first traverse element of the second frame work when the two frame works are respectively in a first and second relative position. An inflexible removable traverse element is attached to the first frame work and to a first portion of the metal bracelet. A locking band attached to a second portion of the metal bracelet passes under the first traverse and is engageable with the spur when the frame works are in the second relative position and further passes through a space defined by the inflexible removable traverse element and a second traverse element on the first frame work when the frame works are in the first relative position.

Abstract: A bracelet for connection to a watch casing, having a lug with a retaining boss, includes a band with a hollow housing across one end. The hollow housing has a wide opening for receiving the lug. A captive resilient element in the housing is deflectable therein to pass the lug and is releasable to a lug retaining position for engagement with the boss.

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.
