Abstract
Abstract A spring clip including parallel jaws carried by telescopically interengaged carrier members. The jaws are spring biased toward one another by a compression coil spring captured between opposed end caps on the carrier members. One of the carrier members has diametrically aligned slots formed through opposed side walls thereof to enable the other member to passed through said slots and snapped into telescopic receipt within said one member. The end caps are formed integrally with the carrier members. In assembly of the clip, the carrier members are passed into telescopic engagement with the end caps in place and the compression coil spring interposed between the end caps.
