Abstract
Abstract A combined releasable holder and lock for electrical connections and cables comprises a pair of identical, strip-like flexible members. Each has a first narrow end or tongue (16), a second wide end or head portion (18), and an intermediate portion with serrations (12 and 14) on its opposite sides. The longitudinal axis of the member has a longitudinal slot (30) which is long enough to pull a cord (39 or 41) with a standard electrical plug (32) or receptacle (34) therethrough. The head portion (18) has a transverse slot (20) formed therein. The member has, on both sides of the transverse slot, two side slots (22 and 24) which converge in a direction opposite to the tongue (16). The end of the long slot (30) nearest the transverse slot (20) terminates in a hole (28). The slots (20, 22, and 24) in the head portion form bendable flaps (23 and 25). The plug and the receptacle are pulled through the longitudinal slots of two members, and then the tongue of one is pulled through the transverse slot of the second, while the tongue of the second is pooled through the transverse slot of the first member. When both tongues are pulled, the serrations bend the flaps out and pass through the material of the strip in one direction but cannot easily pass in the opposite direction. The plug and receptacle are firmly clamped between both straps.
