An enclosure for retaining an electrical connection between a receptacle from a first electrical cord and a plug from a second electrical cord comprises a lower shell hingedly attached to the upper shell and a latch for securing the upper and lower shells into a closed position. In a first embodiment, an inside surface of one or both of the shells may include an elongated protrusion extending into the enclosure interior space for deformably engaging lateral surfaces of the receptacle and plug, thereby creating a frictional force to resist connection separation. The enclosure may also include protrusions or sectional annuli for engaging the first and second cords for resisting cord movement during the application of tensile loads on the electrical connection. Finally, the enclosure may also include a sheath fixed to the receptacle or plug. The sheath includes a retractable protrusion for releasably engaging a crenelated portion on an side surface of the enclosure to secure on portion of the connection, and at least one gripping protrusion engages one of the electrical cords to secure the entire connection within the enclosure.

An improved chalk line marking device for placing chalk marks at regularly spaced intervals along a straight line on a workpiece includes a composite tape having a central layer of porous material receptive to chalk. Upper and lower layers overlying the first layer have smooth surfaces substantially non-receptive to chalk. Holes are formed in the upper and lower layers at regularly spaced intervals through which the underlying portions of the central chalk-receptive layer are exposed. The composite tape is normally stored in a housing and is extensible through an aperture in the housing. The tape is chalked as it is withdrawn through the aperture, the chalk being received by the portions of the central layer exposed through the holes in the upper and lower layers, but the chalk is not absorbed by the smooth upper and lower layers. When the tape is stretched along the desired line and snapped against the workpiece, chalk is transferred from the portions of the central chalk-receptive layer exposed through the holes in the smooth outer layers onto the workpiece to provide chalk marks on the workpiece at regularly spaced intervals.
