Claims: What is claimed is:

1. An adjustable combination lock safe which can be set to a plurality of discrete lock combinations to provide limited and variable access thereto comprising:

telescoping inner and outer members defining in assembly relationship a compartment adapted to secure contents therewithin;

shackle means releasably carried by the outer member for retaining the safe on a mounting member;

first lock means carried by the inner member adapted to be actuated to lockingly engage the shackle means to prevent separation thereof;

actuating means carried by the inner member operable upon telescopic insertion into the outer member to actuate the first lock means to effect locking engagement with the shackle means;

second lock means lockingly engagable between the inner and outer members to prevent telescopic separation thereof;

adjustable combination lock means operatively connected to the second lock means for unlocking the latter upon dialing a predetermined changeable code to permit separation of the members and thereby provide access to the contents therewithin.

2. The key safe according to claim 1 wherein the adjustable combination lock means includes an adjusting knob disposed within the compartment which can be adjusted to vary the lock combination.

3. The key safe according to claim 1 wherein the inner and outer members are formed from deformable sheet metal stamping whereby attempted forced separation of the members will deform the members into a more secure engaged relationship.

4. The key safe according to claim 2 wherein the combination lock means includes a plurality of interengaging discs defining a discrete combination for effecting release of the second lock means, one of which can be angularly changed by the adjusting knob to vary the lock combination according to a predetermined schedule.

5. The key safe according to claim 1 wherein the first lock means and the inner member include engaging camming surfaces for camming the first lock means into locking engagement with the shackle means upon insertion of the inner member.

6. The key safe as recited in claim 4 wherein the adjustable combination means includes a rotatable actuating knob which is rotatable only upon operator dialing of the correct lock combination and is operatively connected to the second lock means to retract the latter upon rotation thereof.

7. The key safe as recited in claim 6 wherein the second lock means is operatively connected to the actuating knob by a rack and pinion drive.

8. The key safe as recited in claim 7 wherein the inner member includes releasable clip means for retaining the contents of the safe.

9. The key safe as recited in claim 7 wherein the actuating knob is releasably coupled to the said one disc by a conical friction clutch cone.

10. The key safe as recited in claim 5 wherein the shackle means comprises a U-bolt having legs depending within the outer member which are releasably carried on the outer member by snap rings and which include notches therein engaged by the first lock means to effect the locking engagement.
