The elastomeric member has sufficient elasticity to allow a user to increase the distance of separation between the two strap ends by applying a tension force, while providing enough tension to return the two strap ends to close proximity when the user releases the tension force. The elastomeric member may also have an adjustable elasticity to accommodate different applications with different load forces. ## Claims ### Claim 1 A fastener comprising: a first connector having a first end and a second end; a second connector having a first end and a second end; wherein the first end of the first connector engages and disengages with the first end of the second connector; an elastomeric member attached to and extending between the first end of the first connector and the first end of the second connector to provide a force that holds the first connector and second connector together and limits a separation distance between the first end of the first connector and first end of the second connector; and a first strap end attached to the second end of the first connector; and a second strap end attached to the second end of the second connector. ### Claim 2 (depends on 1) The fastener of claim 1, wherein the elasticity of the elastomeric member is adjustable. ### Claim 3 (depends on 2) The fastener of claim 2, wherein the adjustable elastomeric member comprises at least one of an adjustable strap, a magnetorheological fluid, an electrorheological fluid, electroactive polymer or similar reactive material and a plurality of attachment points for coupling the elastomeric member to each of the first strap end and second strap end. ### Claim 4 (depends on 1) The fastener of claim 1, wherein the elastomeric member removably couples with the first strap end and the second strap end. ### Claim 5 (depends on 1) The fastener of claim 1, wherein the elastomeric member removably couples with the first connector and the second connector. ### Claim 6 (depends on 1) The fastener of claim 1, wherein the elastomeric member provides a tension that brings the first strap end in close proximity to the second strap end. ### Claim 7 (depends on 1) The fastener of claim 1, wherein the elastomeric member has sufficient elasticity to allow for a separation distance of at least 1 inch between the first strap end and the second strap end. ### Claim 8 (depends on 1) The fastener of claim 1, wherein the elastomeric member has sufficient elasticity such that the first strap end and the second strap end can be separated by a distance of at least 1 inch with no more than 10 pounds of force. ### Claim 9 (depends on 1) The fastener of claim 1, wherein the elastomeric member comprises a sleeve. ### Claim 10 (depends on 1) The fastener of claim 1, further comprising an elastomeric material that couples with the elastomeric member to increase elasticity. ### Claim 11 A fastener comprising: a first connector attached to a first strap; a second connector attached to a second strap; an elastomeric member attached to the first connector and second connector; and wherein the elastomeric member provides a force that holds the first connector and second connector together and limits a separation distance between the first connector and second connector. ### Claim 12 (depends on 11) The fastener of claim 11, wherein the elastomeric member comprises a plurality of attachment points that removably couple with at least one of the first connector and the first strap. ### Claim 13 (depends on 12) The fastener of claim 12, wherein the elastomeric member comprises a plurality of attachment points that removably couple with at least one of the second connector and the second strap. ### Claim 14 (depends on 11) The fastener of claim 11, wherein the first connector and second connector magnetically couple together. ### Claim 15 (depends on 11) The fastener of claim 11, wherein the elastomeric member has sufficient elasticity to bring the first and second connectors in close proximity. ### Claim 16 (depends on 11) The fastener of claim 11, wherein the elastomeric member has sufficient elasticity to engage the first and second connectors. ### Claim 17 A fastener comprising: a first connector; a second connector that slidably engages and disengages with the first connector along a path of engagement; an elastomeric member attached to the first connector and the second connector along the path of engagement; wherein the elastomeric member has sufficient elasticity to allow the first connector and the second connector to separate by a first distance when a separation force is applied; and wherein the elastomeric member holds the first connector and second connector together and in alignment for re-engagement. ### Claim 18 (depends on 17) The fastener of claim 17, wherein the first connector comprises an alignment post that slidably engages a channel of the second connector and is sized and dimensioned to maintain the first connector in alignment with the second connector when separated by the first distance.
