Abstract
A separable fastening device is provided comprising a pair of clasping members, each of said members being comprised of a rigid, bendable material having a central aperture extending therethrough and at least one substantially flat edge section, each flat edge section having; (a) an internal angular notch; (b) an external angular notch; and (c) a slot in said edge section connecting with the vertexes of said internal and external angular notches and dividing said edge section into split end portions, said slot having a gap less than the thickness of the edge section of the other of said pair of clasping members.
Claims5
A separable fastening device comprising a pair of clasping members, each of said members being comprised of a rigid, bendable material having a central aperture extending therethrough and at least one substantially flat edge section, each flat edge section having:
- (a) an internal angular notch;
- (b) an external angular notch;
- and
- (c) a slot in said edge section connecting the vertexes of said internal and external angular notches and dividing each edge section into split edge portions, said slot forming a gap having a thickness less than the thickness of the edge section of said other of said clasping members;
- whereby said clasping members are connected by engaging the external angular notches of each of said edge sections;
- rotating at least one of said clasping members toward the other of said clasping members until the split end portions of each edge section are flexed apart axially and oppositely at each slot sufficient to allow lateral movement of one of said members with respect to the other of said members and moving the edge section of at least one of said clasping members inwardly with respect to said other member until said edge section of each of said clasping members enters the central aperture of said other member;
- and whereby said clasping members are disconnected by engaging the internal angular notches of each of said edge sections, rotating at least one of said clasping members toward the other of said clasping members until the said split end portions of each edge section are flexed apart axially and oppositely at said slots sufficient to allow lateral movement of one of said members with respect to the other of said members and moving the edge section of at least one of said clasping members outwardly with respect to the other of said members until the edge section of said one of said clasping members lies outwardly of said edge section of said other of said clasping members.

- and
- (c) a slot in said edge section connecting said internal and external notches and dividing each edge section into split edge portions, said slot forming a gap having a thickness less than the thickness of the edge section of said other of said clasping members;
- whereby said clasping members are connected by engaging the external notches of each of said edge sections;
- rotating at least one of said clasping members toward the other of said clasping members until the split end portions of each edge section are flexed apart axially and oppositely at each slot sufficient to allow lateral movement of one of said members with respect to the other of said members and moving the edge section of at least one of said clasping members inwardly with respect to said other member until said edge section of each of said clasping members enters the central aperture of said other member;
- and whereby said clasping members are disconnected by engaging the internal notches of each of said edge sections, rotating at least one of said clasping members toward the other of said clasping members until the said split end portions of each edge section are flexed apart axially and oppositely at said slots sufficient to allow lateral movement of one of said members with respect to the other of said members and moving the edge section of at least one of said clasping members outwardly with respect to the other of said members until the edge section of said one of said clasping members lies outwardly of said edge section of said other of said clasping members.
