Pyrotechnic variable delay connector

A pyrotechnic delay connector adapted for initiating a detonation wave in an acceptor cord at a variable time interval after said connector receives a shock wave for a donor device, said time interval being adjustable at the blast site and wherein said connector consists essentially of an elongated, hollowed-out body comprising a first attachment means for firmly holding said donor device, an exothermically burning delay composition located within said hollowed-outed out body, an explosive transfer charge abutting said delay compositon and second attachment means for firmly holding said acceptor detonating cord in initiation relationship with said transfer charge and characterized in that said elongated hollowed-out body has a plurality of lightly sealed notches extending from the surface of the body to expose to initiation the delay composition, said notches being spaced at a variety of distances from said transfer charge and said first attachment means being adapted to bring said donor detonating cord into initiation relationship over a selected one of said notches.
