A test shoe adapted to engage a discrete area on a telephone connector block, normally mounted upon a telephone main frame for the purpose of interfacing with a plurality of individual subscriber circuits appearing on the block, either directly, or through protector modules. The establishment of communication with each subscriber circuit involves the engagement of a large number of contact prongs with corresponding circuits, creating substantial frictional contact tending to retain the shoe in position. Means is provided for facilitating the disengagement of the shoe after completion of testing procedures, whereby the friction is conveniently overcome, and the shoe disengaged in a direction perpendicular to the plane of the connector block.
