Abstract
Abstract This disclosure relates to a clasp for gripping free end portions of a strap to maintain a loop thereof tightly engaged around an object, such as a portion of the human body, the clasp including upper and lower casing halves with means for releasably securing the casing halves in superposed relationship to each other to define a passage therebetween through which free end portions of a strap may pass, a clamping lever pivotally carried by the clasp to present one end portion lying at the loop end of the passage whereby to be forceably engaged by the loop when tight so that the other end of the clamping lever clamps the free end portions of the strap between it and one of the casing halves, and the lower casing half having a bridge-like cross bar lying transversely within the passage.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
155 words
A clasp for gripping free end portions of a strap to maintain a loop thereof tightly engaged around an object such as a portion of the human body, said clasp comprising an upper casing half and a lower casing half and means for releasably securing said casing halves in superposed relation to each other to define a passage therebetween through which the free end portions of a strap may pass thereby forming a loop end at one end portion of a clamping lever, said clamping lever being pivotally carried by said clasp to present said one end portion lying at the loop end of said passage whereby to be forcibly engaged by the loop when tight so that the other end of said clamping lever clamps the free end portions of the strap between it and one of the casing halves, said lower casing half having a bridgelike cross bar lying transversely within said passage.
Claim 2
Dependent Claim
155 words
A clasp for gripping free end portions of a strap to maintain a loop thereof tightly engaged around an object such as a portion of the human body, said clasp comprising an upper casing half and a lower casing half and means for releasably securing said casing halves in superposed relation to each other to define a passage therebetween through which the free end portions of a strap may pass thereby forming a loop end at one end portion of a clamping lever, said clamping lever being pivotally carried by said clasp to present said one end portion lying at the loop end of said passage whereby to be forcibly engaged by the loop when tight so that the other end of said clamping lever clamps the free end portions of the strap between it and one of the casing halves, said lower casing half having a bridgelike cross bar lying transversely within said passage.
