Sleeve for insulating solderless terminal

An electrical connector comprising:

• an insulative sleeve having a rear end removably enclosing and adapted to receive therethrough an electrical lead extending substantially perpendicular to a solderless terminal and a solderless connection connecting a lead end of said electrical lead and the solderless terminal
• a body with a first sidewall and a second sidewall, said first and second sidewalls removably enclosing said solderless terminal when said rear end encloses said electrical lead and said solderless connection, and said first and second sidewalls being in fixed relation to each other at all times,
• a leaf connected by a hinge to the first sidewall at the rear end of the sleeve,
• said leaf and rear portions of said first and second sidewalls forming said rear end of said sleeve,
• at least one hole in the second sidewall at the rear end of the sleeve,
• at least one resilient hook, arranged at an end of the leaf opposite to the hinge, having a projection at a free end, the leaf and hook being dimensioned such that the projection on the at least one resilient hook is arranged to engage the at least one hole in the second sidewall from an inside surface of the second sidewall, whereby the leaf covers the rear end of the sleeve when the projection on the at least resilient hook means engages the at least one hole in the second sidewall of the sleeve from the inside surface of the second sidewall.
