Abstract
Improved lock assemblies for locking two construction components together. A pair of tandem male lock assemblies each includes a rigid pin which is reciprocable with respect to a surrounding male socket between an advanced position and a retracted position. Each male lock assembly includes a transversely reciprocable lock adapted to lock the pin in at least one of, and preferably both of, its two positions. All parts of each lock assembly are retained against separation. The locks of the tandem male lock assemblies are connected for joint movement and are adapted so that, when moved from release positions to pin-locking positions, one lock engages its respective pin before the other lock engages its pin. A cooperative pair of tandem female lock assemblies may have identical jointly movable locks.
